What is entropy of the system ?

Explanation

Entropy of a system is a meausre of randomness or disorder of the system. It is a state function. The change in entropy when a system changes from intial to fina state is expresed as :
`Delta S = S_(2) - S_(1) = (q_(re))/(T) = sum S^(@) f("products") - sum S^(@) f("reactanits")`
When both `Delta H and Delta S` increases, reaction is feasible only when temperature is high.
