- 1The slow step determines the rate; the rate law expression is derived from the slow step✓
- 2The slow step determines the rate; the reaction order is derived from the second step
- 3The fast step determines the rate; the reaction order is derived from the first step
- 4The fast step determines the rate; the reaction order is derived from the second step
Correct answer
The slow step determines the rate; the rate law expression is derived from the slow step
