Answer: The value of Keq for the reaction expressed in scientific notation is [tex]1.6\times 10^{-5}[/tex]
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios.
For the given chemical reaction:
[tex]2NOCl(g)\rightarrow 2NO(g)+Cl_2(g)[/tex]
The expression for [tex]K_{eq}[/tex] is written as:
[tex]K_{eq}=\frac{[NO]^2\times [Cl_2]}{[NOCl]^2}[/tex]
[tex]K_{eq}=\frac{(1.2\times 10^{-3})^2\times (2.2\times 10^{-3})}{(1.4\times 10^{-2})^2}[/tex]
[tex]K_{eq}=1.6\times 10^{-5}[/tex]
The value of Keq for the reaction expressed in scientific notation is [tex]1.6\times 10^{-5}[/tex]
