Given information
The formula for the calculation of the entropy of the system
Step-by-step explanation
Step 1.
The explanation for the correct answer:
Option (a.) A reaction in which the entropy of the system increases can be spontaneous only if it is exothermic, is correct.
The formula for the calculation of the entropy of the system gives information about the spontaneity of a reaction.
The entropy of the system increases due to its positive value. The value of entropy being positive indicates that the value of enthalpy is negative. A negative value of enthalpy indicates that the reaction is an exothermic reaction. Exothermic reactions always have a negative free energy change, making the reaction spontaneous and product formation more favorable.
