4NH3(g) + 3O2(g) --> 2N2(g) + 6H2O(g)

Which statement about this reaction is not correct?

1. At equilibrium, Q = Keq

= [N2]2[H2O]6/[NH3]4[O2]3.

2. Removing molecules of water, (H2O), causes the equilibrium to shift toward the products, regardless of the value of Keq.

3. NH3 and O2 are the reactants and N2 and H2O are the products. Their concentrations are used to determine the value of Q.

4. An increase in the number of O2 molecules will cause the value of Q to be greater than Keq.
