Question

a) For the reaction given in Part A, how much heat is absorbed when 2.70 mol of AA reacts? (the image attached) 

b) For the reaction given in Part A, ΔS∘rxn is 39.0 J/K . What is the standard Gibbs free energy of the reaction, ΔG∘rxn?

Calculate the standard enthalpy change for the reaction
2A +B= 2C+ 2D
where the heats of formation are given in the following table:
AH:
(kJ/mol)
Substance
А
-227
В
-397
C
183
D
-499
