Explanation / Answer

Reaction:1:A+B--------------->2D

reaction-2:C------------------------->D

Multiply the reaction-2 with 2 ,2C------------------------->2D

DeltaH=(458 kJ*2)=916 kJ, Delta S=-276 J/K

substract reaction-1 minus reaction2

A+B-2C--------------->2D-2D

net delta H=-663.2 kJ-(916 kJ)=-1579.2 kJ=-1579.2*10^3 J

net delta S=282 J/K-(-276 J/K)=558 J/K

The resultant reaction is A+B--------------->2C

The gibbs energy is deltaH-TdeltaS=(-1579200 J)-(298 K*558 J/K)=-1412916 J

Thus, the gibbs free energy is -1412.916 kJ
