已知Fe(s)+CO2(g)=FeO(s)+CO(g)
问题描述:
已知Fe(s)+CO2(g)=FeO(s)+CO(g)
Fe(s)+CO2(g)=FeO(s)+CO(g) K1
Fe(S)+H2O(g)=FeO(s)+H2(g) K2
co2(g)+H2=CO(g)+H2O(g) K3
K1K2K3之间的关系式是
答
Fe(s)+CO2(g)=FeO(s)+CO(g) K1减去
Fe(S)+H2O(g)=FeO(s)+H2(g) K2等于
CO2(g) - H2O(g)=CO(g)-H2(g) 焓变等于 K1-K2
调整一下,就等于
co2(g)+H2(g)=CO(g)+H2O(g)因此K3=K1-K2
