`100 cm^3` of 1 M `CH_3COOH` was mixed with `100 cm^3` of 2 M `CH_3OH` to form an ester. The change in the initial rate if eachsolution is diliuted with equal volume of water would be

Options

A. 0.25 times
B. 0.5 times
C. 4 times
D. 2 times

Answer

A

Explanation

When solution is diverted with equal volume of water, concentraton is reduced to half.
`:.r_2 = K (1/2) (2/2) = K/2" "r_1/r_2 =(2K)/(K//2) = 4 rArr r_2 = r_1/4 = 0.25r_1 `
