For `PCl_(5)(g)hArrPCl_(3)(g)+Cl_(2)(g),` write the expression of `K_(c)`

Explanation

To write the expression for the equilibrium constant \( K_c \) for the reaction:

\[ \text{PCl}_5(g) \rightleftharpoons \text{PCl}_3(g) + \text{Cl}_2(g) \]

we will follow these steps:

### Step 1: Identify the products and reactants
In the given reaction, the reactant is \( \text{PCl}_5 \) and the products are \( \text{PCl}_3 \) and \( \text{Cl}_2 \).
