A reaction, `A+B to C+D+q` is found to have a positive entropy change. The reaction will be-

A

possible at high temperature

B

possible only at low temperature

C

not possible at any temperature

D

possible at any temperature

Text Solution

Verified by Experts

The correct Answer is:
D
Thermochemical equation for the reaction indicates that the reaction is exothermic. So, for this reaction, `DeltaH lt 0`. It is given that `DeltaS gt0` for the reaction. So, according to the relation `DeltaG=DeltaH-TDeltaS,DeltaG` will be `lt0` at any temperature. hence, the reaction is possible at any temperature.
