(D) The rate law for the esterification reaction is $Rate = k[CH_3COOH][CH_3OH]$.In the first case,the total volume is $100 	ext{ cm}^3 + 100 	ext{ cm}^3 = 200 	ext{ cm}^3$.In the second case,each solution is diluted with an equal volume of water before mixing. Thus,$100 	ext{ cm}^3$ of acid is diluted to $200 	ext{ cm}^3$ and $100 	ext{ cm}^3$ of alcohol is diluted to $200 	ext{ cm}^3$. When these are mixed,the total volume becomes $400 	ext{ cm}^3$.Since the total volume of the mixture is doubled,the concentration of each reactant ($CH_3COOH$ and $CH_3OH$) becomes half of its initial concentration in the mixture.Let the initial concentrations be $[C_1]$ and $[C_2]$. Then $Rate_1 = k[C_1][C_2]$.In the second case,the new concentrations are $[C_1/2]$ and $[C_2/2]$.$Rate_2 = k[C_1/2][C_2/2] = \frac{1}{4} k[C_1][C_2] = 0.25 	imes Rate_1$.Thus,the rate becomes $0.25$ times the initial rate.

$100 \text{ cm}^3$ of $1 \text{ M } CH_3COOH$ was mixed with $100 \text{ cm}^3$ of $2 \text{ M } CH_3OH$ to form an ester. The change in the initial rate if each solution is diluted with an equal volume of water would be: (in $\text{times}$)
