The equilibrium constants for the reaction, B r 2 ⇌ 2 B r , at 500 K and 700 K are 1 × 1 0 - 10 and 1 × 1 0 - 5 respectively. The reaction is

Options

  1. Aendothermic
  2. Bexothermic
  3. Cfast
  4. Dslow

Correct answer

A. endothermic

Step-by-step solution

As the equilibrium constants for the reaction, B r 2 ⇌ 2 B r , at 500 K and 700 K are 1 × 1 0 - 10 and 1 × 1 0 - 5 respectively it means the value of equilibrium constant is increasing with increase temperature so it is an endothermic reaction.
