3. Chloroethane can be produced by the reaction of ethene with hydrogen chloride: H.C=CH2 + H-C1 → H,C-CH,CU Calculate the standard enthalpy change for this reaction given the following average bond enthalpies. Average bond enthalpy/kJ mol? CEC Bond 612 167 €-C 3471 H-CI E-CI Show your working clearly 4. The equation for the enthalpy of formation of ethene is: 2C(s) + 2H29) C2H4(g) a. Draw the Hess' Law cycle using the combustion reactions for all components b. Use the enthalpies of combustion given in the data booklet to calculate the enthalpy of formation of ethene, in kJ/mol. Show your working clearly
