Question

Write a balanced equation for the combustion of C9H20(l) (nonane)
-- i.e. its reaction with O2(g) forming the products CO2(g) and H2O(l).

Given the following standard heats of formation:

• ΔHf° of CO2(g) is -393.5 kJ/mol
• ΔHf° of H2O(l) is -286 kJ/mol
• ΔHf° of C9H20(l) is -229.0 kJ/mol

-6172.5 kJ

Calculate the difference, ΔHE(PV) for the combustion reaction of 1 mole of nonane.
(Assume standard state conditions and 298 K for all reactants and products.)
