A reaction has both ΔH and ΔS negative. The rate of reaction:
Updated On: Jul 12, 2024
- (A) Increases with increase of temperature
- (B) Increases with decrease of temperature
- (C) Remains unaffected by change of temperature
- (D) Cannot be predicted for change in temperature

The Correct Option is A
Solution and Explanation
Explanation:
A reaction has both ΔH and ΔS negative. The rate of reaction increases with increase of temperature.There is no relation between spontaneity and rate of reaction as rate of reaction is the measure of how fast is the product formed and spontaneity refers whether the reaction occurs with release of free energy which is set at the specified temperature.Spontaneity has no connection with speed of the reaction taking place. Although, in order to increase the rate of the reaction the temperature should be increased as it provides activation energy to the molecule for collision.Hence, the correct option is (A).
