DeltaH and DeltaS for a reaction are +30...

`DeltaH` and `DeltaS` for a reaction are `+30.558 kJ mol^(-1)` and `0.066 kJ mol^(-1)` at `1` atm pressure. The temperature at which free energy is equal to zero and the nature of the reaction below this temperature are

A

483 K, spontaneous

B

443 K, non-spontaneous

C

443 K, spontaneous

D

463 K, non-spontaneous

Text Solution

Verified by Experts

The correct Answer is:
D
Negative value of `DeltaG` indicates that the process is spontaneous. Spontaneous process leads to the lowering of free energy `(Delta G)`.
