The formation of ammonia from elemental nitrogen and hydrogen is an exothermic process.

                  N2(g) + 3 H2(g) ⇌ 2 NH3(g)                                 ΔH = -92.2 kJ

How would a system initially at equilibrium respond in order to counteract each of the following changes? Answer with “runs to the right”, “shifts to the left”, or “no effect”.

a) addition of hydrogen ______________________________________

b) removal of ammonia ______________________________________

c) increasing the pressure _____________________________________

d) increasing the temperature __________________________________

e) removal of nitrogen ________________________________________

f) addition of a catalyst _______________________________________
