Chapter 9.1, Problem 3P

(a)

Interpretation Introduction

Interpretation:

How the rate of the reaction between bromomethane and hydroxide ion be affected when the concentration of the alkyl halide is not changed and the concentration of the nucleophile is tripled has to be explained.

Concept Introduction:

The relationship between the rate of the reaction and concentrations of the given nucleophile and alkyl halide can be represented as follows.

$\text{Rate}\text{α }\left[\text{alkyl halide}\right]\left[\text{nucleophile}\right]$

Thus,

$\text{rate}\text{=}\text{k[alkyl}\text{halide][nucleophile]}$ ,

Where, k is the rate constant.

(b)

Interpretation Introduction

Interpretation:

How the rate of the reaction between bromomethane and hydroxide ion be affected when the concentration of the alkyl halide is cut in half and the concentration of the nucleophile is not changed has to be explained.

Concept Introduction:

The relationship between the rate of the reaction and concentrations of the given nucleophile and alkyl halide can be represented as follows.

$\text{Rate}\text{α }\left[\text{alkyl halide}\right]\left[\text{nucleophile}\right]$

Thus,

$\text{rate}\text{=}\text{k[alkyl}\text{halide][nucleophile]}$ ,

Where, k is the rate constant.

(c)

Interpretation Introduction

Interpretation:

How the rate of the reaction between bromomethane and hydroxide ion be affected when the concentration of the alkyl halide is cut in half and the concentration of the nucleophile is doubled has to be explained.

Concept Introduction:

The relationship between the rate of the reaction and concentrations of the given nucleophile and alkyl halide can be represented as follows.

$\text{Rate}\text{α }\left[\text{alkyl halide}\right]\left[\text{nucleophile}\right]$

Thus,

$\text{rate}\text{=}\text{k[alkyl}\text{halide][nucleophile]}$ ,

Where, k is the rate constant.
