What is the correct characteristic of the photochemistry reaction?
Compared with the general thermochemical reaction, the biochemical reaction has the following characteristics: 1. Many biochemical reactions can increase the Gibbs free energy of the system, such as the transformation of oxygen into oxygen under the effect of light, the decomposition of nitrogen, the synthesis of carbon dioxide and water in plants and the release of oxygen, etc. The Gibbs free energy of thermal reactions is less than 0, and the Gibbs free energy of biochemical reactions may be more than 0. 2. The activation energy of a biochemical reaction comes from the energy of the photon, which is usually about 30kJ/mole, which is smaller than the activation energy of a general thermochemical reaction, and the temperature coefficient of the reaction is small. 3. The photochemistry reaction was a reaction under the effect of light. It was a reaction of excited molecules. 4. In a photochemical reaction, when molecules are activated by light, they can be selectively excited (including the choice of energy transition value, the choice of electronic excited state mode, etc.). The distribution of molecular energy in the system is non-equilibrium distribution, so the path and products of photochemical reactions are often different from thermochemical reactions. 5. As long as the light had the appropriate wave-length and could be absorbed by the substance, even at a very low temperature, the biochemical reaction could still be carried out. The temperature had little effect on the photochemistry and could be ignored. The thermochemical reaction was very sensitive to temperature. 6. Photochemical reactions and thermochemical reactions also had different kinetic properties. The activation of the reagent molecules was achieved by absorbing light quantum. The rate and equilibrium composition of the biochemical reaction are related to the intensity of the absorbed light (la), sometimes unrelated to the concentration of the reagent. The rate constant of the thermal reaction is relatively large, while the rate constant of the biochemical reaction is very small, sometimes close to 0. Read more exciting novels for free
Fighting through the firmament, Xiao Yan's woman's age
The age of Xiao Yan's woman was as follows: - Xun Er was about the same age as Xiao Yan. Xiao Yan was about a year older than Xun Er.

Xun Er's final age was also thirty years old. - Medusa was already more than 300 years old when she appeared. - Yun Yun was 18 years old when Xiao Yan made the three year agreement. Yun Yun was at least 18 years older than Xiao Yan and was at most 30 years old. There was also information that indicated that when Xiao Yan first had an ignorant feeling towards Yun Yun, Yun Yun was already over 30 years old. - The Fairy Doctor was a few years older than Xiao Yan. When Xiao Yan was in his thirties, the Fairy Doctor was probably around forty years old. - Qing Lin appeared to be only ten years old.

Which price is lower, including tax or not?
The tax - included price is calculated by multiplying the tax - excluded price by (1 + tax rate). So generally, the tax - excluded price is lower than the tax - included price. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the reactions and symptoms after the colonic stent surgery?
The following symptoms may occur after a colonic stent: 1. ** Abdominal-related symptoms ** - Due to the risk of intestinal puncture and bleeding, abdominal symptoms and signs should be closely observed in the short term. If the intestine was punctured, there might be signs of inflammation, such as tenderness, rebound tenderness, fever, and sudden elevation of blood count. - It was necessary to pay attention to the defecation and exhaust to determine whether the intestinal obstruction stent was effective in relieving the intestinal obstruction. It was also necessary to closely observe whether there was blood in the stool and the amount of blood in the stool. 2. ** Digestive system symptoms ** - There might be pain and discomfort; - After the placement of the intestinal stent, the bacteria in the intestine may multiply around the stent, leading to intestinal infection. - The stent may move or be blocked by tumor tissue or feces, causing the symptoms of intestinal obstruction to recur. 3. ** Other symptoms **: Since there is a risk of tumor spread after stent placement for intestinal obstruction, if necessary, intravenous chemotherapy is needed to prevent tumor spread. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Counting the singers on the stage who were robbed of their mic
It was not uncommon for singers to have their microphones snatched onstage. For example, when Ding Dang sang "The Same Moonlight" at a concert in Shanghai, a female fan rushed to the stage to grab the microphone because her child was missing. She shouted incoherently to the fans below the stage, causing chaos at the scene and forcing the singing to be suspended. When the Korean singer Xu Ge was singing at the university outdoor music festival, a nearby resident rushed onto the stage and snatched the microphone away. The resident said that Xu Ge's singing was too noisy and affected his sleep. He even wanted to hit someone. Fortunately, the staff stopped him in time, so Xu Ge was able to continue the performance. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Haoyi Store broadcasted overseas
Due to the country's policy restrictions on genre dramas such as modified dramas, dramas such as " Hao Yi Xing " faced difficulties in broadcasting. On the overseas software, QQ Video announced the posters of 10 new dramas, including " Haoyi Store." This indicated that " Haoyi Store " had plans to broadcast overseas. However, this was also a way for the platform to recover its losses. At present, there was no specific information on its overseas broadcast. The original work is equally wonderful.
