Rate Law Mechanism 10 Consider the reaction, H 2 + I 2 => 2 HI , which is found to be half order in I 2 and first order in H 2 . Which step of the proposed mechanism must be slow in order to agree with this rate law? I 2 => 2 I I + H 2 => H 2 I H 2 I + I => 2 HI Student Response Value Correct Answer Feedback 1. 1 0% 2. 2 100% 3. 3 0% 4. Either 2 or 3 0% Score: 0/1 2.
