Van't Hoff's equation for a chemical reaction under equilibrium is given by standard reaction enthalpy at temperature T and K is the equilibrium constant. Predict how K will vary with temperature for an exothermic reaction.

Options

  1. AK decreases as the temperature rises
  2. BK remain unchanged
  3. CK increases as the temperature rise
  4. DInformation is not sufficient

Correct answer

A. K decreases as the temperature rises

Step-by-step solution

Here K decreases as the temperature rises as K ∝ 1 T .
