The temperature of the equilibrium mixture is lowered. The pressure acting on the equilibrium mixture is held constant. Describe how and explain why the position of equilibrium changes.
The pressure on the equilibrium mixture is raised. The temperature of the equilibrium mixture is kept unchanged. Explain why the change in pressure has no effect on this equilibrium.
