(a) Interpretation: The alkane (methane, ethane, propane or butane) which evolves the greatest amount of heat during combustion on the basis of per mole should be determined. Concept introduction: The standard enthalpy of combustion can be defined as the heat change for the combustion of one mole of substance that leads to the formation of carbon dioxide and water. The standard enthalpy of combustion can be calculated with the help of enthalpy of formation of reactant and product molecules. ΔHcombustion = ∑ ΔHf(product) - ∑ ΔHf(reactant)

Solution Summary: The author defines the standard enthalpy of combustion as the heat change for the combustion of one mole of substance that leads to the formation of carbon dioxide and water.
Definition Definition Simplest organic compounds that contain only single bonds between carbon – carbon atoms and carbon – hydrogen bonds. This means they are a series of saturated compounds with a general molecular formula, C n H 2n+2 .
