In a pseudo first order hydrolysis of ester in water, the following results were obtained:

Calculate the average rate of reaction between the time interval 30 to 60 seconds.

Text Solution

Verified by Experts

Average rate
` ( Delta x)/( Delta t) = ( x_1 -x_2)/( t_2 - t_1) = ( 0.31 - 0.17 )/(60-30 ) = ( 0.14 )/( 30)`
`= 4.67 xx 10^(-3) Ms^(-1)`
