The Total solution for NCERT class 6-12
Enthalpy of combustion of carbon to CO2 is –393.5 kJ mol–1. Calculate the heatreleased upon formation of 35.2 g of CO2 from carbon anddioxygen gas.
Formation of CO2 from carbon anddioxygen 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
