Effect of concentration change Change in concentration is directly affected by equilibrium. If the concentration of the reactant increase, the equilibrium is disturbed. If the concentration of the product increases, the equilibrium is disturbed.
The endothermic reactionin which heat chatellers absorbed and is favored at high temperature.
And with the rise in temperature, the equilibrium will shift towards the backward direction and the concentration of the product is decreased. For Endothermic Reaction According to the principle, if the temperature is decreased in an endothermic reaction chateliets equilibrium shift from backward direction and a result of this concentration of products is decreasing. And with the rise in temperature, the equilibrium will shift from the forward direction and the concentration of the product is increased.
Effect of concentration change
Effect of Pressure Change Change in pressure only affects gaseous equilibrium because the change in pressure is related to the change in volume. Pressure has no effect on solids and liquids because they are almost incompressible, hence their volumes are very little affected by the change in pressure. Effect of Catalyst A catalyst has no effect on the equilibrium.
It increases the rate of reaction by lowering the energy of activation and enables equilibrium to be reached more quickly.]
