A reaction A → B , involves following mechanism Step 1 A → k 1 B ( f a s t ) Step 2 B → k 2 C ( s l o w ) Step 3 C → k 3 D ( f a s t ) The rate law of the reaction may be given as
Options
- Arate = k 1 [ A ]
- Brate = k 2 [ B ]
- Crate = k 3 [ C ]
- Drate = k 1 k 2 k 3 [ B ] [ C ]
Correct answer
B. rate = k 2 [ B ]
Step-by-step solution
As the slowest step is rate determining step. So rate = k 2 [ B ] .
