On mixing 1 dm3 of 3 M ethanol with 1 dm3 of 2 M ethanoic acid, an ester is formed.
C2H5OH+CH3COOHCH3COOC2H5+H2O
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

detailed solution

Correct option is B

r=kCH3COOHC2H5OH or r=knVnVIncreasing volume (V) by twice (due to dilution) will reduce the rate by 4 times. i.e. r=0.25kCH3COOHC2H5OH
