On increasing temperature, the equilibrium constant of exothermic and endothermic reactions, respectively

Options

  1. Aincreases and decreases
  2. Bdecreases and increases
  3. Cincreases and increases
  4. Ddecreases and decreases

Correct answer

B. decreases and increases

Step-by-step solution

For exothermic reaction, k_f decreases and k_b increases with increase of temperature so that K_ e q decreases. For endothermic reaction, k_f increases and k_b decreases with increase of temperature so that K_ e q increases.
