As we learnt

Pseudo-first order reaction -

If one reactant is present in large excess a 2nd order reaction is converted to 1st order reaction. This is called a pseudo first order reaction.

- wherein

acid catalysed hydrolysis of ester

C_{3}H_{6}O_{2}+H_{2}O\rightarrow CH_{3}COOH+CH_{3}OH

This reaction is first order with respect to ester. The 2nd order reaction with respect to that reactant which has been taken in more amount .e.g.

r=k[CH_{3}CO_{2}CH_{3}][H_{2}O] =k^{'}[CH_{3}CO_{2}CH_{3}]

 k[H_{2}O]=k^{'}

 

 


Option 1)

Option 2)

Option 3)

Option 4)
