Equilibrium

• change in concentration • presence of catalyst • change in pressure

• pressure that would be exerted by a gas • in a mixture of gases • if it occupied the same volume on its own • at the same temperature

mole of component/ total amount of moles in mixture

mole fraction x total pressure of mixture KPa

• sum of partial pressures of components in equilibrium • is equal to total pressure

• amount in moles of a component • in a mixture • divided by the total moles • of all the components

• equilibrium shifts to left • concentration reactants increases • Kc decreases

• equilibrium shifts to right • concentration products increases • Kc increases
