A chemical reaction is spontancous at `298 K` but non spontaneous at `350 K` . Which one of the following is true for the reaction ?

Options

A. `{:(Delta G,DeltaH ,DeltaS),(-,-,+):}`
B. `{:(Delta G,DeltaH ,DeltaS),(+,+,+):}`
C. `{:(Delta G,DeltaH ,DeltaS),(-,+,-):}`
D. `{:(Delta G,DeltaH ,DeltaS),(-,-,-):}`

Answer

D

Explanation

As reaction is spontaneous at low temperature and non-spontaneous at high temperature,i.e., `DeltaG` is-ve at low temperature and `+ve` at high temperature and `DeltaG =DeltaH - T DeltaS`, only ( e) in correct.
