Question

Predict the effect of the following changes in the reaction CO (g) + 2 H2 (g) <-> CH3OH (g) + energy.

Answer 1

Explanation:

  Equation of reaction:

             CO   + 2H₂    ⇒   CH₃OH   +   energy

a.  An increase in pressure:

A change in pressure affects only equilibrium involving a gas or gases. Le Chatelier's principle can be used to predict the direction of displacement.

An increase in pressure on an equilibrium system will shift the position of equilibrium to the side having smaller volume and vice-versa

       CO   + 2H₂    ⇒   CH₃OH   +   energy

          3 moles                  1 moles

An increase in pressure will favor the forward reaction to be favored.

b. Addition of H₂:

An in concentration of a specie favors the direction that uses up that specie and lowers its concentration.

Addition of hydrogen gas increases the concentration of amount of substances reacting.

To annul the effect of the reactant, more the product is given. The equilibrium shifts in the forward direction.
