Question

At equilibrium, the concentrations of the different species are as follows.

[NH3] = 0.105 M
[N2] = 1.1 M
[H2] = 1.50 M

What is the equilibrium constant for the reaction at this temperature?

Answer 1

write the equilibrium expression for the equation (this needs to be written prior), plug in your values and solve.

Answer 2

@aaronq is correct, you need to write the equation that occurs, then use the formula for calculating an equilibrium constant value
