(3pts) Briefly in the space below, state how you identified the best mechanism. !"#$%&'()&&*+,'#-"( FOR MECHANISM #3 6. (2 pts) Write the overall balanced equation predicted by the correct mechanism. I2 + H2 2HI 2 pts for perfect equation, +1 if still contained some intermediates 7. (4 pts) Based on the mechanism you chose, write the rate law for the overall reaction and state the overall reaction order. Rate = k[I2][H2] 3 pts: Perfect 2 pts: Substituted CORRECTLY for 1 intermediate, but not both 1 pts: Started with correct step, did not substitute for intermediates Overall reaction order: 2nd order 1 pt, based on rate law AS WRITTEN 8.
