Expert Solution
Step 1
Equilibrium reactions are governed by Le Chatelier principle, which states that - A system at equilibrium counteracts any changes that disturb the equilibrium.
If we are increasing the concentration/partial pressure of the reactants, the system in order to decrease it shifts the reaction to the forward direction. Similarly, if we increase the concentration/partial pressure of the products, the system in order to decrease it and regain the equilibrium shifts the reaction in the backward direction.
If you increase the volume, the reaction shifts to the side which contains higher number of gaseous molecules.
If you decrease the volume the reaction shifts to the side which contains lower number of gaseous molecules.
