Question

Consider the reactions below. In which cases is product formation favored by decreased temperature?

1) CO(g) + 3 H2(g)  CH4(g) + H2O(g); ΔHo = -206.2 kJ
2) CO2(g) + C(s)  2 CO(g); ΔHo = 172.5 kJ
3) H2(g) + I2(g) 2 HI(g); ΔHo = -9.4 kJ
4) 3 O2(g)  2 O3(g); ΔHo = 285 kJ
5) 2 H2O(g)  2 H2(g) + O2(g); ΔHo = 484.6 kJ
