MCQ
From the given data at $298\,K$ 

$\Delta H_f^o[CO_2,g] = -394 \,kJ/mol$ 

$\Delta H_f^o[H_2O,l] = -286\, kJ/mol$ 

$\Delta H_f^o [propene ,g] = 20\,kJ/mol$ 

cyclopropane $(g)$ $\to$ propene $(g)$ ; $\Delta H^o_{isomerisation} = $ $-33\,kJ/mol$.
Calculate $\Delta H^o_{combustion}$ [cyclopropane, $(g)$]
