C. is at equilibrium.
Expert Solution
Step 1
Nitrogen gas reacts with hydrogen gas to form ammonia:
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:
