What can help overcome a positive enthalpy of solution and allow a solid solute to dissolve in water?
A. A decrease in entropy
B. A large amount of energy released
C. A large amount of energy absorbed
D. An increase in entropy

D. An increase in entropy

Explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from  an disordered arrangement to an ordered arrangement, the entropy is said to increase and vice versa.

For a reaction to be spontaneous, the enthalpy of the solution must decrease and the entropy must increase.

To overcome a positive enthalpy of solution and allow a solid  solute to dissolve in water, an increase in entropy would make the reaction spontaneous as the system would move to a more disordered state.
