Gibbs Free Energy For Combustion of Octane
Not what you're looking for?
Calculate delta G combustion at 25'C of octane, c8H18(l),
2C8H18(l) + 25 O2(g) -------> 16 CO2(g) + 18 H2O(l)
Using the following thermodynamic data and that given in textbook.
For C8H18(l), delta H formation = - 208.4 kJ mol-1 and delta S = 463.71 JK-1 mol-1. Give your answer in kJ mol-1 of C8H18 (l).
