A Pseudo first-order reaction can be defined as a second-order or bimolecular reaction that is made to behave like a first-order reaction. This reaction occurs when one reacting material is present in great excess or is maintained at a constant concentration compared with the other substance.

What is pseudo order reaction give example?

Thus, the reaction appears to be first order, but it is actually of second order that's why known as pseudo first order reaction. So, concentration of water can be approximated as constant as its concentration doesn't change a lot during the reaction. thus, hydrolysis of cane sugar is pseudo first order reaction.

What is pseudo first order of reaction?

A reaction which is not first-order reaction naturally but made first order by increasing or decreasing the concentration of one or the other reactant is known as Pseudo first order reaction. Pseudo means 'fake'.
