The equilibrium constant for the reaction A ⇌ B is K. The equilibrium constant for the reaction mA ⇌ mB is 1) mK 2)K/m 3) Kᵐ 4) K⁻ᵐ

Equilibrium constant depends on,

1. Temperature 2)Stoichiometric Coefficient 3) direction of reaction..

1. Temperature :

* For an exothermic reaction ( H < 0), equilibrium constant is inversly proportional to temperature. Increasing temperature decreases Kcd. Decreasing the temperature increases Kc.

* For an endothermic reaction ( H > 0). Equilibrium constant is directly proportional to temperature. Increasing temperature increases [Kc; decreasing temperature decreases Kc.

* If (H = 0) (there is no heat effect of temperature),  Kc is independent of temperature.
