The average bond enthalpy for c−h is 413 kj/mol. 413 kj of energy is required to break a mole of ch into atoms: ch(g)→c(g)+h(g), δh=413 kj using this information, and your answer from part a, calculate the enthalpy change of the reaction from part b. that is, calculate the energy required to break only the carbon-carbon bonds in benzene. express your answer to four significant figures and include the appropriate units.
