When at equilibrium, which of the reactions below will shift to the right if the pressure is increased and the temperature is kept constant?

A. 2SO3(g) ↔ 2SO2(g) + O2(g)
B. 2CO2(g) ↔ 2CO(g) + O2(g)
C. 2H2(g) + O2(g) ↔ 2H2O(g)
D. 2NO(g) ↔ N2(g) + O2(g)

Correct Answer:

Option C – 2H2(g) + O2(g) ↔ 2H2O(g)
