- equilibrium
- change in temperature
- If temperature increases, equilibrium will shift to counteract the change
- When delta H is negative, equilibrium shifts to the left
- When delta H is POSITIVE, equilibrium shifts to the RIGHT
- change in pressure
- greater moles of GAS = higher pressure
- If pressure increases, equilibrium will shift to counteract the change
- the position of equilibrium will move the the side with the LEAST moles of GAS (least pressure)
- change in concentration
- Adding more acid increases the concentration of H+ ions
- Equilibrium will shift to counteract the effect of increase in H+ ions
- Position will move the opposite direction to where there was an increase in H+ ions
- Catalysts
- have no effect on the position of the equilibrium
- the equilibrium is reached faster
- change in temperature
- Le Chatelier's Principle States "if a system is subject to a change, the equilibrium shifts to minimise the effect of the change.
