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 first-order reaction can be defined as a chemical reaction for which the reaction rate is entirely dependent on the concentration of only one reactant. In such reactions, if the concentration of the first-order … bambam taeyeon
