Question
**Understanding the Effect of Solvent Volume on Reaction Rate:**

Consider the following reaction: 
\[ \text{CH}_3\text{Br} + \text{HO}^- \rightarrow \text{CH}_3\text{OH} + \text{Br}^- \]

The question addresses the effect of doubling the volume of the solvent on the reaction rate. The potential factors by which the reaction rate could be multiplied include:

- 1/4
- 4
- 1/2
- 2

**Visual Explanation:**

In the reaction provided:
- \(\text{CH}_3\text{Br}\) represents methyl bromide.
- \(\text{HO}^-\) represents hydroxide ion.
- \(\text{CH}_3\text{OH}\) represents methanol.
- \(\text{Br}^-\) represents bromide ion.

The choices given (1/4, 4, 1/2, 2) are factors by which the reaction rate might change when the volume of the solvent is doubled. Understanding the impact of solvent volume on reaction rate is essential in fields such as chemistry and chemical engineering.

In a typical reaction, changes in concentration can significantly impact the reaction rate due to the relationship defined by the rate law and overall reaction kinetics. For instance, for reactions that are second-order (rate dependent on the concentration of two reactants), doubling the volume (and thus halving the concentration of each reactant) can reduce the reaction rate by a factor of 1/4.

To determine how doubling the solvent volume affects this specific reaction’s rate, analyze the reaction order and the sensitivity of the reaction rate to changes in concentration.
