Expert Answer

Step 1

The equation connecting Gibbs free energy, enthalpy, entropy and temperature is

fullscreen
Step 2

Freezing of water indicates that the physical state changes from liquid to solid. Thus the value of entropy will be negative since entropy is the degree of disorderness. Also the freezing of water is an exothermic reaction and hence the value of enthalpy will be negative.

Step 3

At –10 degree Celsius, the Gibbs free energy will be ...
