Answer:

Explanation:
For a process that occurs at constant temperature and pressure, spontaneity can be determined using the change in Gibbs free energy, which is given by:
ΔG = ΔH - TΔS. A process is spontaneous if ΔG≤O.
Even so the enthapy of the dissolution is positive the factor -TΔS will produce a negative ΔG value. As ΔS is relatived to the disorder of a system, a increase in this value (ΔS ) upon dissolution will made the dissolution process spontaneous.
