From the following data, calculate the enthalpy change for the combustion of cyclopropane at `298K`. The enthalpy of formation of `CO_(2(g)),H_(2)O_((l))` and `Propen e_((g))` are `-393,-285.8` and ` 20.42 kJ mol^(-1)` respectively. The enthalpy of isomerisation of cyclopropane to propene is `-33.0kJ mol^(-1)`

`C_(3) H_(6) + 4.5 O_(2) rarr 3CO_(2) + 3H_(2)O " "Delta H = ?`
`Delta H = 3 xx 393.5 + 3 xx -285.8 - 20.42 - 33 = -2091 . 32 kJ`.
