The rate of a reaction is given as , rate ` = k[X]^(3//2) [Y]^(-1//2)`
What is the order of the reaction ? If Y is taken large in excess , write the rate equation.

Explanation

To solve the problem, we need to determine the order of the reaction given the rate equation and then write the rate equation when one of the reactants is in excess.

### Step-by-Step Solution:

1. **Identify the Rate Law**:
The rate of the reaction is given as:
\[
\text{rate} = k [X]^{\frac{3}{2}} [Y]^{-\frac{1}{2}}
