Estimate ΔHrxn for the following chemical reaction using the bond enthalpies in the table found here. Report your answer to zero decimal places in standard notation (i.e. 123. kJ *For numbers ending in zero, be sure to include the decimal!*

Homework Answers

Answer #1

Hrxn = Hproducts - H reactants

H0 C2H4 = 52.4 KJ/mole

H0 Cl2 = 0 KJ/mole

H0 C2H4Cl2 = -125.4 KJ/mole

Hrxn = Hproducts - H reactants

Hrxn = -125.4 - (52.4+0) = 73.0 KJ/mole
