Enter your answer in the provided box. Acetylene (C2H2) and benzene (C6H6) have the same empirical formula. In fact, benzene can be made from acetylene as follows: 3C2H2(g) → C6H6(l) The enthalpies of combustion for C2H2 and C6H6 are −1299.4 kJ/mol and −3267.4 kJ/mol, respectively. Calculate the standard enthalpies of formation of C2H2 and C6H6. Assume that the products of the combustions are CO2(g) and H2O(l). ΔH o f (C2H2) = kJ/mol ΔH o f (C6H6) = kJ/mol Calculate the enthalpy change for the formation of C6H6 from C2H2. ΔHrxn = kJ/mol
