Calculate the enthalpy change for the following reaction, in kJ mol-1

N2O4(g) + Cl2(g) →  2NOCl(g) + O2(g)

given the following data:                                       ∆H (kJ mol-1)

2NOCl(g)  → 2NO(g) + Cl2(g)                              +75.56

2NO(g) + O2(g)  → 2NO2(g)                                -113.05

2NO2(g)     → N2O4(g )                                         -58.03
