Question: Consider the overall reaction H2 + Br2 > 2HBr, which is believed to proceed through the following mechanism: k1 Br2 2Br (fast) k1 k2 Br

Consider the overall reaction H2 + Br2 > 2HBr, which is believed to proceed through the following mechanism: k1 Br2 2Br (fast) k1 k2 Br + H2 H2Br (fast) k2 k3 H2Br + Br 2HBr (slow) Based on the mechanism above, write the rate law for this reaction. (Show your work!) Also explicitly indicate the expression for kobs in terms of k1, k-1, k2, k-2, and/or k3. (You will need to derive a rate law expression. Hint: Build on the approach we developed for mechanisms that have a rate-determining second step and fast equilibria as the first step.)
