A reaction is spontaneous at low temperature, but non-spontaneous at high temperature. Which of the following condition is true for the chemical reaction?

Options

  1. AH 0, S 0
  2. BH 0, S=0
  3. CH 0, S 0
  4. DH 0, S 0

Correct answer

A. H 0, S 0

Step-by-step solution

H 0, S 0 G= H-T S When, H 0 and S 0 , then G will be negative only at low temperature.
