We’re being asked to determine the heat of combustion (in kJ/mole) of ethane, C2H6.
Recall that ΔH˚rxn can be calculated from the enthalpy of formation (ΔH˚f) of the reactants and products involved:
For this problem, we need to do these steps:
Step 1: Write the balanced equation for the combustion reaction of ethane
Step 2: Calculate the ΔH˚combustion
What is the heat of combustion of ethane, C2H6, in kilojoules per mole of ethane?
