(a)
Interpretation:
The change in number of moles of carbon dioxide while adding solid
Concept introduction:
Le Chatelier's principle states that if a system in equilibrium gets disturbed due to modification of concentration, temperature, volume, and pressure, then it reset to counteract the effect of disturbance.
(b)
Interpretation:
The change in number of moles of carbon dioxide while adding water vapor has to be explained.
Concept introduction:
Le Chatelier's principle states that if a system in equilibrium gets disturbed due to modification of concentration, temperature, volume, and pressure, then it reset to counteract the effect of disturbance.
(c)
Interpretation:
The change in number of moles of carbon dioxide while decreasing the volume of container has to be explained.
Concept introduction:
Le Chatelier's principle states that if a system in equilibrium gets disturbed due to modification of concentration, temperature, volume, and pressure, then it reset to counteract the effect of disturbance.
Effect of change in pressure:
- According to Le Chatelier's principle, increase in pressure leads to flow of reaction in direction where number of moles is less.
- According to Le Chatelier's principle, decrease in pressure leads to flow of reaction in direction where number of moles is more.
(d)
Interpretation:
The change in number of moles of carbon dioxide while increasing temperature has to be explained.
Concept introduction:
Le Chatelier's principle states that if a system in equilibrium gets disturbed due to modification of concentration, temperature, volume, and pressure, then it reset to counteract the effect of disturbance.
Effect of change in temperature:
Endothermic reaction: In this reaction increase in temperature which is absorbed in reactant side, the reaction occurs in a way to relieve the stress in reactant side. The reaction occurs along the direction of product side and increases equilibrium constant.
Exothermic reaction: In this reaction increase in temperature which is released in product side, the reaction occurs in a way to relieve the stress in product side. The reaction occurs along the direction of reactant side and decreases equilibrium constant.
