Thermodynamics is not concerned about….

A

Energy changes involved in a chemical reaction

B

The extent to which a chemical reaction proceeds

C

The rate at which a reaction proceeds

D

The feasibility of a chemical reaction

Text Solution

Verified by Experts

The correct Answer is:
C
Thermodynamics is not concemed with the rate at which a reaction proceeds. Thermodynamics deals with the energy change, feasibility and extent of a reaction, but not with the rate and mechanism of a process.
