Question:

The rate for the reaction

RCl + NaOH → ROH + NaCl is given by rate = k[RCl]. Which of the following statement is correct?

Options:

The rate of reaction is doubled on doubling the concentration of NaOH.

The rate of reaction is halved on reducing the concentration of RCl to half.

The rate of reaction is decreased on increasing the temperature of the reaction.

The rate of reaction is unaffected by increasing the temperature of the reaction.

Correct Answer:

The rate of reaction is halved on reducing the concentration of RCl to half.

Explanation:

As the rate of reaction depends only on the concentration of RCl, hence rate of reaction is halved on reducing the concentration of RCl to half.
