1. State the equation for the formation of ethane, C2H6, from its elements and then determine the value for the standard enthalpy of formation of ethane given the following standard enthalpies of combustion. Carbon (graphite): -394 kJ mol-1, hydrogen: -286 kJ mol-1and ethane: -1560 kJ mol-1.2. The values for the enthalpies of combustion of carbon (graphite) and hydrogen can be used to determine the enthalpy of formation...
