WebMay 23, 2024 · Best answer The reactions which are not truly of first order but become reactions of first order under certain conditions are called pseudo first order reactions. For example, hydrolysis of ester. Rate = k’ [CH3COOC2H5] [H2O] Since water is in excess and [H2O] is constant, so Rate = k [CH3COOC2H5], where k = k’ [H2O] ← Prev … WebA few example for pseudo first-order reaction are : 1. Hydration of Alkyl halide. CH 3 I + H 2 O gives CH 3 OH + H + + I -. Rate of reaction = k [CH 3 I] [ H 2 O], where, k is the rate constant. methyl iodide is also used in an aqueous solution. Hence, the concentration of water is higher than that of methyl iodide.
