Propenenitrile (acrylonitrile) is used in the manufacture of synthetic fibres and nitrile rubber. It can be made from propane using the following gas phase reaction :CH2=CH−CH3+NH3+3/2O2→CH2=CH−CN+3H2OCalculate (in kJ) values corresponds to the standard enthalpy change for this reaction? Assume that the combustion of both reactants and products yields CO2,H2O and N2, and that the enthalpy changes of combustion are ΔHΘc[CH2=CH−CH3]=−2058.0kJmol−1,ΔHΘc[NH3]=−382.8kJmol−1,ΔHΘc[CH2=CH−CN]=−1756.4 kJmol−1 |
