Answer:
1.6x10^–5
Explanation:
Step 1:
The balanced equation for the reaction.
This is illustrated below:
2NOCl <=> 2NO + Cl2
Step 2:
Data obtained from the question.
[NOCl] = 1.4x10^–2 M
[NO] = 1.2x10^–3 M
[Cl2] = 2.2x10^–3 M
Equilibrium constant, K =?
Step 3:
Determination of the equilibrium constant.
The equilibrium constant for the above equation can be written as:
K = [NO]^2 [Cl2] / [NOCl]^2
Inputing the values of the [NO], [Cl2] and [NOCl], the equilibrium constant is:
K = [NO]^2 [Cl2] / [NOCl]^2
K = (1.2x10^–3)^2 x (2.2x10^–3) / (1.4x10^–2)^2
K = 1.6x10^–5
