## Answers ( )

Answer:(a): The expression of equilibrium constant is(b): The equation to solve the concentration of NO is(c): The concentration of NO is 0.0017 M.Explanation:The

equilibrium constantis defined as the ratio of the concentration of products to the concentration of reactants raised to the power of the stoichiometric coefficient of each. It is represented by the term(a):

The given chemical equation follows:

The expression for equilbrium constant will be:

(b):

The equation to solve the concentration of NO follows:

……(1)

(c):

Given values:Plugging values in equation 1, we get:

Hence, the concentration of NO is 0.0017 M.
