Explain the fact that a small amount of Nal catalyzes the general reaction
`R - CI + R ' - O^(Theta) Na to R - O R + NaCI`
With `I^(-) ` ion the overall reaction occurs in two steps each of which is faster than the uncatalyzed reaction .

Explanation

To explain how a small amount of NaI catalyzes the reaction between an alkyl halide (R-Cl) and sodium alkoxide (R'-O^(-) Na) to form an ether (R-O-R') and sodium chloride (NaCl), we can break down the process into two main steps. Each of these steps is faster than the uncatalyzed reaction.

### Step-by-Step Solution:

1. **Understanding the Reaction**:
The overall reaction can be represented as:
\[
R - Cl + R' - O^{-} Na \rightarrow R - O - R' + NaCl
