Answer 1

C)

Delta H° = -131 KJ = -131000 J

Delta S° = -262 J/K

T = 308K

Delta G(rxn) = Delta H(rxn) - T * Delta S(rxn)

Delta G(rxn) = -131000 - 308 * (-262) = -50304 J = - 50.03 KJ .....Answer

Part G)

Since, Delta G° is negative and hence reaction is spontaneous.

D)

Delta G° = - 131000 - 557 * (-262) = 14934 J = 14.93 KJ ...Answer

H)

Since Delta G° is positive and hence reaction is non spontaneous.
