Question
State a condition under which a bimolecular reaction is kinetically first order reaction.
Advertisements
Solution
Let us consider a biomolecular reaction:
\[\ce{A + B -> Product}\]
Rate = k[A] [B] ...(i)
When concentration of [B] is taken in large excess, rate law will become Rate = k'[A]
Where, k' = k[B]
The order of reaction will be equal to one.
