Question

What would cause the equilibrium to shift left in this reaction?

CO + 3H2 ⇌ CH4 + H2O

A) adding heat to the product mixture

B) a faster rate of forward reaction

C) increased collisions between CO and H2

D) the escape of water from the mixture

E) placing the mixture in a cold water bath

Answer 1

Explanation:

Answer: Option A. Explanation: To decrease pressure by increasing volume, the equilibrium of the reaction shift to the left as the reactant side has greater number of moles than the product side
