What is Le Chatelier's principle?
- It is also known as equilibrium law, are used to predict the effect of some changes on a system in chemical equilibrium
- When factors like concentration, pressure, temperature, inert gases that affect equilibrium are changed, equilibrium will shift in that direction where the effects caused by these changes are nullified.
1. Increasing concentration of CO:
The concentration of product CO2(g) increases and the concentration of reactants, CO(g) and O2(g) decreases
2. Increasing concentration of CO2:
The concentration of reactants, CO(g) and O2(g) increases and concentration of the product, CO2(g), decreases
3. Decreasing the volume of system: The concentration of the product, CO2(g) increases and the concentration of the reactants, CO(g) and O2(g) decreases
Explanation:
Given reaction: 2CO(g) + O2(g) -->2CO2(g)
1. Increasing concentration of CO:
When the concentration of reactant CO(g), increases; the equilibrium shifts towards the forward direction or product side, thereby increasing the concentration of product, CO2(g) and decreasing the concentration of the reactants, CO(g) and O2(g).
2. Increasing concentration of CO2:
When the concentration of the product CO2(g), increases; the equilibrium shifts towards backward direction or reactant side, thereby increasing the concentration of the reactants, CO(g) and O2(g) and decreasing the concentration of product, CO2(g).
3. Decreasing the volume of the system
When the volume of the system decreases, the pressure increases, thus causing the equilibrium of reaction to shift in a direction that produces less number moles of gas.
Since, total number of moles of gaseous reactants is 3 and products is 2
Therefore, when the volume of system decreases; equilibrium of the reaction shifts towards the forward direction or product side, thereby increasing the concentration of the product, CO2(g) and decreasing the concentration of the reactants, CO(g) and O2(g).
