Expert Solution
Step 1

Nitrogen gas reacts with hydrogen gas to form ammonia:

Chemistry homework question answer, step 1, image 1

At the given state the concentration of different species is as follows:

N2 = 4.18x10-2 M

H2 = 3.79x10-2 M

NH3 = 5.18x10-4 M

Note the volume of the solution is one liter, hence the concentration of all reactants and products is equal to the moles of these species.

Step 2

The value of the reaction quotient is given by:
