Answer: The equilibrium constant for the reaction is 0.000016.
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric coefficients.
The given balanced equilibrium reaction is,
[tex]2NOCl(g)\rightleftharpoons 2NO(g)+Cl_2(g)[/tex]
The expression for equilibrium constant for this reaction will be,
[tex]K_c=\frac{[NO]^2[Cl_2]}{[NOCl]^2}[/tex]
Now put all the given values in this expression, we get :
[tex]K_c=\frac{(1.2\times 10^{-3})^2\times (2.2\times 10^{-3})}{(1.4\times 10^{-2})^2}[/tex]
[tex]K_c=0.000016[/tex]
Thus the equilibrium constant for the reaction is 0.000016.
