Calculate ΔrxnS, ΔrxnH, and ΔrxnG at 298Kfor the reaction below:
2 C3H6 (g) -----------------> C2H4 (g) + C4H8 (g)
DH of C3H6 = 20.42 kj/mole
DH of C2H4 = 52.3Kj/mole
DH of C4H8 = -15.8
DH of reaction = [DH of products] - [DH of reactents]
= [-15.8+52.3] - [2*20.42]
= 32.16 KJ
........................................................................................................................
DS of recation = [DS of products] - [DS of reactents]
= [219.56 + 298.83] - [2*267.05]
= - 15.71 Kj
.............................................................................................................................
DG of reaction = DH of reaction - T*Ds of reaction
= 32.16 -[298*(-15.71)]
= 4713.74 KJ
