0.16 g of methane was subjected to combustion at `27^(@)` C in a bomb calorimeter. The temperature of calorimeter system (including water) was found to rise by `0.5^(@)` C. Calculate the heat of combustion of methane at (i) constant volume and (ii) constant pressure. The thermal capacity of the calorimeter system is `17.7 kJ K^(-1)`.

Answer

`q_(v) = - 885 kJ mol^(-1) , q_(p) = -890 kJ mol^(_1)`
