The enthalpy change of combustion of alcohols Aim The aim of this experiment is to investigate the enthalpy change of combustion for a variety of alcohols and determine how the number of carbon atoms affects the combustion of the alcohol. 'The standard enthalpy change of combustion is the enthalpy change when one mole of an element or compound reacts completely with oxygen under standard conditions. For example a pressure of 100 kilopascals, a temperature of 298 Kelvin, solutions must have a concentration of 1.0 mol/dm3 and also the reactants and products must be in the physical states e.g. solid, liquid or gas, that are normal for these conditions.'1. An example of a combustion reaction of methane is show below. CH4(g) + 2O2 CO2 (g) + 2H2O(l) Prediction & Development of problem I predict that the enthalpy change of combustion will increase as the number of carbon atoms within the alcohol increases. Alcohols form a homologous...
