  • Rate of reaction, <img alt="\mathrm{ A+2 B \rightarrow Product~ is =k[B]^2[A]}" src="https://entrancecorner.oncodecogs.com/gif.latex?%5Cmathrm%7B%20A&plus;2%20B%20%5Crightarrow%20Product%7

Rate of reaction, \mathrm{ A+2 B \rightarrow Product~ is =k[B]^2[A]} . If B is taken in large excess, then the order of reaction is:

Option: 1

Pseudo second order


Option: 2

Pseudo first order 


Option: 3

First order 


Option: 4

Second order

Pseudo order reaction:
A reaction whose order is different from the actual due to excess concentration of one of the reactants is called pseudo-order reaction.

\mathrm{A+2 B \rightarrow P }

\mathrm{Rate, R=k[B]^2[A] }

When B is taken in excess, then the reaction will be independent of [B] and is dependent on [A].

Here, the reactions are third order but behave as first order reactions. This reaction is called pseudo first order reaction.
