A reaction A +B rarr C+D +q is found to ...

A reaction `A +B rarr 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
Here, `DeltaH=-ve` and `DeltaS=+ve, DeltaG=DeltaH-TDeltaS`. For the reaction to be spontaneous, `DeltaG` should be -ve which will be so at any temperature, i.e., option (iv) is correct.
