The standard enthalpy change for the reaction below is -2391.7 kJ (for the reaction as written). What is the standard enthalpy of formation of WC(s)?

2 WC(s) + 5 O2(g) –> 2 WO3(g) + 2 CO2(g)

Give your answer in kilojoules per mole (kJ mol-1), accurate to one decimal place. Do not include units in your answer.
