The standard Gibbs energy of formation of the product C(g) is -8.4 kJ/mol (this value is negative!) at 25 'C. Find the new reaction Gibbs energy (in J/mol) when the partial pressures of A, B and C are 7, 4 and 11 bar, respectively

A5 mole sample of liquid acetone is converted to a gas at 75.0°c. if 628 j are required to raise the temperature of the liquid to the boiling point, 15.600 kj are required to evaporate the liquid, and 712 j are required to raise the final temperature to 75.0°c, what is the total energy required for the conversion?
