Based on Le Chatelier's principle, if the equilibrium of a given system is disturbed by inducing a change in the temperature, pressure or concentration, then the equilibrium will shift in a direction to undo the effect of the change induced.
The given equilibrium is:
2CO(g) + O2(g) ↔ 2CO2(g)
a) If the concentration of CO (reactant) is increased, then the equilibrium will shift to a direction which would lower the concentration of CO i.e. in the forward direction. Therefore,
[CO2] will increase
[CO] and [O2] will decrease
b) If the concentration of CO2 (product) is increased, then the equilibrium will shift to a direction which would lower the concentration of CO2 i.e. in the reverse direction. Therefore,
[CO2] will decrease
[CO] and [O2] will increase.
The concentration of species in the reaction changes the reaction in the following ways:
The direction of the reaction can be assessed by the following. On increasing the concentration of the reactant the reaction processes in the forward direction. On increasing the concentration of product the reaction processes in the backward direction.
increase CO = forward direction of reaction
increase oxygen = forward direction of reaction
decrease CO = no change in equilibrium as reaction not processes.
decrease oxygen = no change in equilibrium as reaction not processes.
increase carbon dioxide= reverse direction
decrease carbon dioxide = forward direction of reaction.
