Given the reaction: N2 + O2 = 2NO for which the Keq at 2273 K is 1.2 x 10-4 a. Write the equilibrium constant expression for the reaction.
b. Write the equation that would allow you solve for the concentration of NO.
c. What is the concentration of NO if [NZ] = 0.166M and [02] = 0.145M?

(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 constant is 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.

most likely he is cheating on you

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
