The Standard Enthalpy of Combustion of nonane (C9H20), a major component of kerosene, is -6125 kJ mol-1.

a) Define the Standard Enthalpy of Combustion, cHo, of a substance.

b) Define the terms Exothermic and Endothermic and state which term applies to the Standard Enthalpy of Combustion of nonane.

c) Write down the balanced chemical equation for which the enthalpy change is the Enthalpy of Combustion of nonane.

d) Determine the enthalpy change when 2.0 kg of nonane is burnt in an excess of oxygen. [Ar(C) = 12.0, Ar(H) = 1.0]

e) For every kg of nonane that is burnt, what volume of CO2 is produced? Assume SATP conditions for which the molar volume of a gas is 24.8 dm3 mol-1.

f) Use the following data to determine the Enthalpy of Formation, fHo, of nonane: fHo(CO2) = -393.5 kJ mol-1, fHo(H2O) = -286.0 kJ mol-1.
