Question

What is water gas equilibrium reaction?​

Answer 1

The water-gas shift reaction is an equilibrium process: CO +H2O(g) ↔ CO2 +H2 [R1. 6]. The forward reaction is exothermic (ΔH°R=−41.0 MJ/kmol), converting carbon monoxide and steam to hydrogen and carbon dioxide. The forward reaction is active at temperatures lower than 700°C.

Answer 2

ANSWER

K=

[H

2

O(g)]

[CO(g)][H

2

(g)]

Concentration will increase, on halving the volume. There are two terms in numerator. So to keep K constant, concentration of [H

2

O] should increase
