Question

Top fuel dragsters and funny cars burn nitromethane (CH3NO2) as fuel according to the following balanced combustion equation:

2CH3NO2(l) + 3/2O2(g) → 2CO2(g) + 3H2O(l) + N2(g)   ΔcH = −709.2 kJ mol−1

Calculate the standard enthalpy of formation, ΔfH°, for nitromethane.
Express your answer to one decimal place.

You can find a table of standard enthalpies of formation (ΔfH°) for the other reactants and products on ACORN (Appendix IIB: Standard Thermodynamic Quantities).
