Enthalpy of combustion of carbon to CO2 ...

Enthalpy of combustion of carbon to `CO_2` is `-393.5 kJ mol^(-1)`
Calculate the heat released upon formation of 35.2 g of `CO_2` from carbon and dioxygen gas.

Text Solution

Verified by Experts

`underset(1 mol =44 g)(C(s) +O_(2)(g)rarr CO_(2)(g), DeltaH=-393.5 kJ mol^(-1))`
Heat relased when `44 g CO_(2)` is formed `=393.5 kJ`. Therefore, Heat released whrn `35.2 g CO_(2)` is formed
`393.5/44xx35.2 kJ =314.8 kJ`
