Kc and temperatureMediumQuestion 600409

Question

For an endothermic reaction, increasing temperature:
  1. A
    Decreases Kc
  2. B
    Increases Kc
    Correct
  3. C
    No change in Kc
  4. D
    Shifts equilibrium left

Correct answer

Increases Kc

Explanation

By van't Hoff equation: d(lnK)/dT = ΔH°/RT². For endothermic ΔH° > 0 → K increases with temperature.
