Consider a reaction

A+R \rightarrow

Product. The rate of this reaction is measured to be

k[A][R]

. At the start of the reaction, the concentration of

R,[R]_0

, is 10-times the concentration of

A,[A]_0

. The reaction can be considered to be a pseudo first order reaction with assumption that

k[R]=k^{\prime}

is constant. Due to this assumption, the relative error (in %) in the rate when this reaction is

40 \%

complete, is

\underline{\hspace{2cm}}

. [

k

and

k^{\prime}

represent corresponding rate constants]
