What is the chemical equation for the reaction that represents breaking all the

Question

Explanation / Answer

Well first you have to write down the equation of the breakin of benzene. which is C6H6 --> 6C+ 3H2. Once you have that equation is really easy to find enthalpy, which is products minus reactant. In this case by the given information the enthalpy of formation of C6H6 is 82.9. the enthalpy of formation for 6C is (718.4)*6 plus the enthalpy of 3H2 which is (217.94)*6 addin both of them up the enthalpy of formation of the products comes up to be 5618.04. Now that you have that you do as i mention earlier products-reactact, meaning 5681.04-82.9 your answer will come out to be 5535 kJ.
