Identify the correct statement from the following in a chemical reaction

Answer»

The entropy always increases.
The change in entropy along with suitable changein enthalpy DECIDES the fate of a REACTION.
The enthalpy always decreases.
Both the enthalpy and the entropy remains constant.

Solution :`DELTA G = Delta H- T Delta S`
For a reaction to be spontaneous `Delta G`should be NEGATIVE. Thus `Delta S` and `Delta H`decides the fate of a reaction.
