An endothermic reaction is found to have + ve entropy change. The reaction will be

Options

  1. Apossible at high temperature
  2. Bpossible only at low temperature
  3. Cnot possible at any temperature
  4. Dpossible at any temperature

Correct answer

A. possible at high temperature

Step-by-step solution

Given, S=+ ve and H=+ ve ( For endothermic reaction) Now, G= H-T S For a reaction to be spontaneous, G should be -ve which is possible only at high temperature i.e., when T S> H .
