The value of ^G for the following reaction is -5490 kJ. Use this value and data to calculate the standard free energy of formation for C4H10 (g).

2 C4H10 (g) + 13 O2 (g) --> 8 CO2 (g) + 10 H2o (l)

Do you know the heats of formation for CO2 and H2O?

Wouldn't delta G/2, minus 4 Hfco2, minus 5 Hfh2o, equal Hfbutane?

    heat of formation for CO2(g) is -393.5 kJ/mol and for H2O(l) it's -285.8 kJ/mol
