Seeking help regarding vinyl reactions

The requests for assistance are as follows: 1) Find the activation energies for several elementary reactions, as follows: C2H4Cl2 ——> C2H4 + 2 Cl* (that is, 1,2-dichloroethane breaks down into ethylene and 2 chlorine radicals); C2H4 ——> C2H3* + H* (that is, ethylene breaks down into a vinyl radical and a hydrogen radical); 2 C2H3* ——> C4H6 (that is, 2 vinyl radicals combine to form 1,3-butadiene). 2) Please recommend any books or materials that provide information on reactions involving vinyl radicals. Thank you! Note: $ # $ $
HappyDay has explained it
I spent a long time looking at the materials but still didn’t understand them; I’m sorry, haha!
Take a seat and wait for an expert to explain~~~
For example, use * to represent an unpaired single electron； C2H3Cl + C2H3* ——> C4H6 + Cl* That is: vinyl chloride + vinyl radical ——> 1,3-butadiene + chlorine radical ； For the activation energy of this reaction, the value I found is E = 9157 kcal/kmol. I would like to get information regarding the first three reactions ； Thank you~
