Question

The heat of formation of co2 and so2 are -394.55 and -290.7KJ .the heat of combustion of cs2 is -1071.2KJ .calculate heat formation of CS2

Answer 1

Answer:

The heats of formation of CO2(g) and H2O(l) are – 393.5 and – 285.8 kJ ..... SO2(g) ∆H = – 295.4 kJ 290 8 PHYSICAL CHEMISTRY Subtracting equation (ii) .... The heat of combustion of CS2, Sulphur and Carbon are –26.5 kcal, –94.3
