I need help with "e)" and "f)"

Given these steps of a mechanism: Cl242C1 Cl + CHCl3 + HCl + CCl3 Cl + CCl3 CCl4 The first reaction is fast. The rate constants are ki for the foward direction and k-1 for the reverse. The second reaction is slow and has a rate constant k2. The third reaction is slow and has a rate constant of k3. e) Use the variables above and sticking to the order that reactants appear in the balanced chemical equations, write out the rates of the individual steps. For example, k5[CC13]4[HCl] would represent the rate for k5[CC13]4[HCI]. Hint: This is case-sensitive and you must use [X] to indicate concentration. r1 = r-1 = r2 = r3 = f) Work out the mechanism to arrive at the final rate expression. Once done, report the overall order here, and if the overall order is indeterminate, type -100
