Problem: What is the heat of combustion of ethane, C2H6, in kilojoules per mole of ethane?

FREE Expert Solution

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

$\overline{){\mathbf{∆}}{\mathbf{H}}{{\mathbf{°}}}_{{\mathbf{rxn}}}{\mathbf{=}}{\mathbf{∆}}{\mathbf{H}}{{\mathbf{°}}}_{\mathbf{f}\mathbf{,}\mathbf{products}}{\mathbf{-}}{\mathbf{∆}}{\mathbf{H}}{{\mathbf{°}}}_{\mathbf{f}\mathbf{,}\mathbf{reactants}}}$

For this problem, we need to do these steps:

Step 1Write the balanced equation for the combustion reaction of ethane

Step 2: Calculate the ΔH˚combustion
