Calculate the enthalpy of formation of Benzene represented by following reaction:
6C + 2H2 gives C6H6
The standard enthalpy of combustion of Benzene is -3266.0 kJ and standard enthalpy of formation of CO2 and H2O are -393.1 kJ and -286.0 kJ respectively.
According to the given information
Method to solve the problem:
The heat required equation can be obtained by algebraic method.
Multiply reaction (ii) by 6 and reaction (iii) by 3 and write (i) in reverse form. Add all the three equation.
Hence, the enthalapy of formation of benzene is 49.4 kJ.
