The equilibrium boiling point of ethanol, CH3CH₂OH, is T = 78°C at P = 1.00 atm. What are the signs of AG and AS univ for the process of boiling 1.00 mole of liquid ethanol under the following conditions? (a) T = 50°C and P = 1.00 atm AG >0 and ASuniv <0; at temperatures below the boiling point, liquid ethanol will not boil. (b) T = 78°C and P = 1.00 atm AG=0 and ASuniv = 0; at the boiling point, boiling liquid ethanol is a reversible process. (c) T = 90°C and P = 1.00 atm AG<0 and ASuniv> 0; at temperatures above the boiling point, liquid ethanol will boil.
