Consider the following system at equilibrium: N2(g) + 3H2(g) <--> 2NH3 (g)
What will happen to this system if 1.00 mol N2 is suddenly added?

a. The sudden change in the amount of N2 increases the rate in the reverse direction to compensate and produce more H2.

b. The additional collisions between N2 and H2 molecules increases the rate in the forward direction and produces more NH3

c. As the concentration of NH3 increases, equilibrium shifts to the left and increases H2 concentration.

d. The concentrations of each molecule would increase relative to the original amount present.
