What trend in ionization energy occurs across a period on the periodic table? What causes this trend?

A reaction vessel contains nh3, n2, and h2 at equilibrium at a certain temperature. the equilibrium concentrations are [n2] = 0.31 m, [h2] = 1.51 m, and [nh3] = 0.75 m. calculate the equilibrium constant, kc, if the reaction is represented as
