The reaction of chloroform, CHCl3 and chlorine, Cl2, forms carbon tetrachloride, CCl4 and HCl with the following possible mechanism: a. Cl2(g) ---> 2 Cl(g) fast b. Cl(g) + CHCl3 > HCl(g) + CCl3g) slow c. CCl3(g) + Cl(g) > CCl4(g) fast What are the intermediates for this reaction? What is the rate law?
