Question

What is pseudo frist order reaction ? Explain with example.

Answer 1

If one of the reactants is used in a very large excess... A pseudo first order reaction is a reaction that is truly second order but can be approximated to be first order under special circumstances. For example, a second order reaction of the type A + B --> C is dependant on the concentrations of both A and B.

Answer 2

A + B —-> C +d

where [A] and [B] are the reactants of the chemical reaction expressed in units of concentration (moles per liter), k is the rate constant, and x and y are the exponents that are called the reaction orders of the individual reactants.
