Answer

Explanation:

Step1: Recall equilibrium - constant expression

For a general reaction (aA + bB\rightleftharpoons cC + dD), the equilibrium - constant (K=\frac{[C]^c[D]^d}{[A]^a[B]^b}), where ([X]) represents the molar concentration of species (X).

Step2: Identify reactants and products and their coefficients

For the reaction (COCl_2(g)\rightleftharpoons CO(g)+Cl_2(g)), the reactant is (COCl_2) with a coefficient of 1, and the products are (CO) and (Cl_2) each with a coefficient of 1.

Step3: Write the equilibrium - constant expression

Using the formula from Step 1, we have (K = \frac{[CO][Cl_2]}{[COCl_2]}).

Answer:

(K=\frac{[CO][Cl_2]}{[COCl_2]}) (corresponding to the third option in the multiple - choice list)
