What are the reasons for the reaction phenomenon in the blast furnace ironmaking experiment?在高炉炼铁实验中: 1. **氧化铁与一氧化碳反应方面** - 反应\(Fe_{2}O_{3}+3CO = 2Fe + 3CO_{2}\),其中氧化铁(\(Fe_{2}O_{3}\))被一氧化碳(\(CO\))还原为铁(\(Fe\)),这一反应发生的原因是一氧化碳具有还原性,它能夺取氧化铁中的氧元素,从而使铁被还原出来。从化学键角度看,一氧化碳中的碳氧键在反应过程中发生断裂,氧化铁中的铁氧键也发生断裂并重新组合形成二氧化碳。 2. **碳和氧气反应方面** - 反应\(C+O_{2}=CO_{2}\)(放出热量),碳(\(C\))与氧气(\(O_{2}\))反应生成二氧化碳(\(CO_{2}\))并放出热量。这是因为碳具有可燃性,在有氧气存在且达到反应条件时就会发生燃烧反应,该反应是氧化反应,碳的化合价从0升高到 + 4价,氧气的化合价从0降低到 - 2价,通过化学键的断裂与重组释放出能量,为炼铁反应提供高温条件。 3. **碳与二氧化碳反应方面** - 反应\(C + CO_{2}=2CO\)(吸热反应),这个反应是可逆反应,并且自下而上发生在高炉中所有有焦炭的地方。碳(\(C\))与二氧化碳(\(CO_{2}\))反应生成一氧化碳(\(CO\)),该反应之所以是吸热反应,是因为反应过程中要破坏二氧化碳分子中的碳氧双键,需要吸收能量来克服化学键能,生成的一氧化碳可以作为炼铁的还原剂。 4. **高炉气中一氧化碳含量方面** - 高炉炼铁所排出的高炉气中总会含有相当数量的一氧化碳,原因是铁矿石用一氧化碳还原,生成铁和二氧化碳的反应是可逆反应。当这种还原反应达到平衡时,也就是正逆反应速率相等的时候,反应物与生成物保持动态平衡,此时增加反应时间,也改变不了反应物与生成物的百分含量,所以高炉煤气中一氧化碳含量约为28 - 33%。 <a...
