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

On increasing temperature, the equilibrium constant of exothermic and endothermic reactions, respectively
  1. increases and decreases
  2. decreases and increases
  3. increases and increases
  4. decreases and decreases

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. /
