On mixing 1 dm^(3) of 3M ethanol with 1 ...

On mixing 1 `dm^(3)` of 3M ethanol with 1 `dm^(3)` of 2 M ethanoic acid, an ester is formed.
`C_(2)H_(5)OH+CH_(3)COOHrarrCH_(3)COOC_(2)H_(5)+H_(2)O`
If each solution is diluted with an equal volume of water , the decrease in the initial rate would be

A

0.5 times

B

4 times

C

0.25 times

D

2 times

Text Solution

Verified by Experts

The correct Answer is:
C
`r=k[CH_(3)COOH][C_(2)H_(5)OH]`
`or" "k=k[(n]/[V)][(n]/[V)]`
Increasing volume (V) by twice (due to dillution) will reduce the rate by 4 times.
`i.e." "r=0.25k[CH_(3)COOH][C_(2)H_(5)OH]`
