Vedclass · Answer

(C) The correct option is $(C)$.
When a concentrated solution of $CuSO_4$ is mixed with a dilute solution of $CuSO_4$,the process is essentially a dilution process.
During dilution,the randomness of the solute particles increases as they spread out in a larger volume,which leads to an increase in entropy $(\Delta S > 0)$.
Since the mixing of two solutions of the same solute at the same temperature involves negligible heat change (ideal mixing approximation),the enthalpy change $(\Delta H)$ is approximately zero.
