Thermodynamics is not concerned about

A

change in energy 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 related with the rate at which a reaction proceeds. Thermodynamics is related with the energy change, feasibility and extent of a reaction, but not with the rate and mechanism of a reaction.

    Entropy ( S ) is a thermodynamic variable like pressure P , volume V and temperature T . Entropy of a thermodynamic system is a measure of disorder of molecular motion. Greater is disorder , greater is entropy. Change in entropy of a thermodynamic system is the ratio of heat supplied to absolute temperature.In an adiabatic reversible process, entropy remains constant while in any irreversible process entropy increases. In nature the processes are irreversible , therefore entropy of universe is continuoulsy increasing. The unit of entropy in S-I system is -
