Answer:

Just to retire this question....the energy change is unknown without data...

Explanation:

We address the reaction....

#CH_4(g) + Cl_2(g) rarr H_3C-Cl(g) + H-Cl(g)#

Now all enthalpy change is determined on the balance between the energies of BONDS FORMED, i.e. #C-Cl# and #H-Cl# bonds, and bonds broken, i.e. #Cl-Cl#, and #C-H# bonds....

..as always...#DeltaH_"rxn"^@-=Sigma_"bonds formed"-Sigma_"bonds broken"#

You could find a table of standard bond enthalpies and make the summation yourself....
