Consider the exothermic reaction 2C2H6(g)+7O2(g)→4CO2(g)+6H2O(g) Calculate the standard heat of reaction, or ΔH?rxn, for this reaction using the given data. Also consider that the standard enthalpy of the formation of elements in their pure form is considered to be zero. Reactant or product ΔH?f (kJ/mol) C2H6(g) -84.7 CO2(g) -393.5 H2O(g) -241.8 Express your answer to four significant figures and include the appropriate units.
