How could you increase the production of 2NH3(g) N2(g) plus 3H2(g) 2NH3(g) Increase the volume of the reaction vessel. Increase the pressure of the system. Decrease the pressure of the system. Remove?

Given N2(g) + 3H2(g) <---> 2NH3(g), increasing the pressure will cause more NH3 to form. According to LeChatelier's Principle, an increase in pressure moves the equilibrium in the direction where there are fewer moles (particles), which in this equilibrium, is to the right.
