Cl2 reacts with H2 according to Cl2 + H2 -> 2HCl Rate= k[H2][Cl2]^(1/2) If the first three step reactions for this reaction are: step 1: Cl2 -> 2Cl step 2: H2 +Cl -> H2Cl step 3: H2Cl + Cl2 -> 2HCl +Cl Assume all the step reactions except the rate determining step are fast reactions and at equilibrium, which step reaction, do you think, is the rate determining step? (a)Cl2 -> 2Cl (b)H2 +Cl -> H2Cl (c) H2Cl + Cl2 -> 2HCl +Cl (d) none of the above (e) not enough information to determine
