In the reaction N2(g) + O(g)
↔ 2NO(g) produced i an increase in the total pressure will?

cause less nitrogen to be produced in the equilibrium mixture

cause less nitric oxide to be produced in the equilibrium mixture

cause more nitric oxide to be produced in the equilibrium mixture

cause more oxygen to be produced in the equilibrium mixture

have no effect

If the pressure is increased, the position of equilibrium. moves in the direction of the fewest moles. of gas

However, because there is an equal number of particles on both sides, change in pressure will have no effect on the system.
