For a reaction, `X_(2) +3Y_(2) rarr 2XY_(3)` write the rate equation in terms of rate of disappearance of `y_(2)`.

Explanation

To write the rate equation for the reaction \( X_2 + 3Y_2 \rightarrow 2XY_3 \) in terms of the rate of disappearance of \( Y_2 \), we can follow these steps:

### Step 1: Write the general rate expression
The rate of a reaction can be expressed in terms of the change in concentration of reactants and products over time. For this reaction, we can express the rate as:

\[ \text{Rate} = -\frac{d[X_2]}{dt} = -\frac{1}{3} \frac{d[Y_2]}{dt} = \frac{1}{2} \frac{d[XY_3]}{dt} \]
