How does a change in temperature affect the composition of an equilibrium mixture?

Options

  1. AIt has no effect on the composition.
  2. BIt always increases the concentration of products.
  3. CIt always decreases the concentration of products.
  4. DIt depends on the sign of ∆H for the reaction.

Correct answer

D. It depends on the sign of ∆H for the reaction.

Step-by-step solution

The composition of an equilibrium mixture is affected by a change in temperature, and the direction of the effect depends on the sign of ∆H for the reaction.
