Question

A- hydrolysis of an ester follows firsr order kinetics
R- concentration of water remains nearly constant during the course of reaction
A- if both are correct
B if both are correct but r is not the reason
C a is correct but r is wrong
D a is wrong but r is correct

Answer 1

Answer:

The reaction that is the hydrolysis of ester happens to be psuedo first order reaction and not an absolute one just because the concentration of water which is present as solvent liquid does not change considerably throughout the course of the reaction and hence it can be said that this hydrolysis reaction is a first order Reaction.

So correct answer is option (A), that is both the statement and it's given reason are correct i.e the given reason happens to be the correct explanation too.

Hope this helps you !
