State a condition under which a bimolecular reaction is kinetically first order reaction.
A condition under which the order of a chemical reaction can be altered is by taking the solvent or the reactant in the excess amount due to which its concentration does not change much.
CH3COOCH3 + H20 ⇌ CH3COOH + CH3OH
Initially, rate is given by,
Rate= k’ [CH3COOH] [H2O]
When we add an excess of solvent then,
Here k= k’[H2O]
This is also known as pseudo first-order reaction.
