The equilibrium expression is written as [NH3]^2/[N2] [H2]^3.
<h3>What is equilibrium constant?</h3>
A reaction involves the conversion of reactants to products. Now we know that the number that shows us the extent to which we can convert the reactants to products is given by the equilibrium constant. If the equilibrium constant is large and positive, then the reaction tends towards the conversion of reactants to products. on the other hand, when the reaction has a small equilibrium constant, then the reaction tends towards the reactants.
Thus, the magnitude of the equilibrium constant tells us how easily reactants are converted into products and this is necessary when we are trying to predict the direction in which a reaction will go or make calculations.
Given a reaction; N₂(g) + 3H₂(g) ----> 2NH3(g) we can now write the expression for the equilibrium of the reaction as;
K = [NH3]^2/[N2] [H2]^3

The percent change in attendance, relative to last year's show is a 5% increase.
<h3>What is a percentage? </h3>
A Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred.
<h3>What is the percentage change in attendance? </h3>
The value of the percentage change in attendance can be determined by subtracting the number of people in this year's show from the number of people at last year's show. The result would be divided by the number of people at last year's show and multiplied by 100.
[(16,800 - 16,000)/16,000] x 100 = 5%
