1. A certain reaction is spontaneous at 43 degrees. If the enthalpy change for the reaction is 21 kj/mol what is the minimum value of delta S in kj/mol?
2. The molar heat of vaporization of ethanol is 39.3 kj/mol, and the boiling point of ethanol is 78.3 C. Calculate delta S for the vaporization of .3 mol ethanol.
