Calculate the free energy change for the following reaction at 13 deg C?

by admin on 05. Apr, 2010 in free energy

C3H8(g) + 5O2 (g)=3CO2(g) + 4H2O(g)
Delta H_rxn = -2217kJ Delta S_rxn = 101.1 J/K.

I believe it is spontaneous, just can’t calculate the free energy change.

Change in free energy is given by the formula.

delta G = delta H – T ( delta s)

delta G = -2217 -( 286 K )* (101.1)

delta G = – 31131.6 JK

spontaneous at all temperature
