The enthalpy change for the reaction
C(π) +\( \frac{1}{2}\) O2(π)βCO(π) is _______ kJ per mole of CO(π) produced.
(rounded off to one decimal place)
[Given:
C(π)+O2(π) β CO2(π), ΞHrxn = β393.5 kJ per mole of CO2(π) produced
CO2(π) β CO(π) +\( \frac{1}{2}\) O2(π), ΞHrxn = 283.0 kJ per mole of CO(π) produced]
