Identify the correct statement in a chemical reaction-

Answer»

the entropy always increases
the change in entropy along with suitable change in enthalpy decides the rate of REACTION
the enthalpy always decreases
both the enthalpy and the entropy REMAINS constant

Solution :For a reaction occurring at a constant TEMPERATURE and pressure, `DELTAG lt 0,` i.e., `DeltaH-TDeltaS lt0`. So, the change in entropy `(DeltaS)` along with the change in enthalpy `(DeltaH)` determines the SPONTANEITY of a reaction.
