For a reaction to be spontaneous at all temperatures

Options

  1. AG and H should be negative
  2. BG and H should be positive
  3. CG= S=0
  4. DH < G

Correct answer

A. G and H should be negative

Step-by-step solution

For a reaction to be spontaneous at all temperature G should be negative. As we know G= H-T S =- ve -T(+ ve )=- ve G and H should be negative.
