Enthalpy of combustion of carbon to CO2 is –393.5 kJ mol–1 . Calculate the heat released upon formation of 35.2 g of CO2 from carbon and dioxygen gas.
Formation of CO2 from carbon and dioxygen gas can be represented as:
(1 mole = 44 g)
Heat released on formation of 44 g CO2 = –393.5 kJ mol–1
Heat released on formation of 35.2 g CO2
= –314.8 kJ mol–1
