The Effect Of Pressure Changes On Equilibrium (ht Only) (GCSE Chemistry)

If the pressure of a system at equilibrium is increased and the position shifts so that more product forms, what happens to the rate at which the new equilibrium is established compared to before the pressure change?

For PCl5(g) ? PCl3(g) + Cl2(g), increasing pressure has which effect on the equilibrium position?

In which industrial situation is raising pressure used despite higher cost because it increases yield of a gaseous product?

An inert gas is added at constant volume to a reacting gas mixture. Which of the following is correct immediately after addition?

In the industrial Haber process for ammonia production, why is a high pressure used?

For the gas-phase equilibrium N2(g) + 3H2(g) ? 2NH3(g), what is the effect of increasing the total pressure (by compressing the container) at constant temperature?

For the equilibrium 2SO2(g) + O2(g) ? 2SO3(g), what is the effect of increasing pressure?

For 2NO2(g) ? N2O4(g) the equilibrium at constant temperature is a brown ? colourless system. What happens to the colour if pressure is increased by compression?

Which statement best describes the effect of pressure changes on reaction rate and equilibrium position?

An inert gas is added to a sealed container holding a gas-phase equilibrium at constant volume and temperature. What is the effect on the position of equilibrium?

Which statement about adding an inert gas at constant pressure (by increasing volume) is correct for a gas-phase equilibrium?
