Answer:
(a) forward direction
(b) forward direction
(c) backward direction.
Explanation:
Given , the chemical reaction in equilibrium is,
SO₂(g) + Cl₂(g) ⇄ SO₂Cl₂ (g)
The direction of the reaction by changing the concentration can be determined by Le Chatelier's principle,
It states that ,
When a reaction is at equlibrium , Changing the concentration , pressure, temperature disturbs the equilibrium , and the reaction again tries to attain equilibrium by counteracting the changes.
(a)
For the reaction , Cl₂ is added to the system , i.e. , increasing the concentration of Cl₂ ,Now, according to Le Chatelier , The reaction will move in forward direction , to reduce the increased amount of Cl₂.
Hence, reaction will go in forward direction.
(b)
Removing SO₂Cl₂ from the system ,i.e. , decreasing the concentration of SO₂Cl₂ , according to Le Chatelier , the reaction will move in forward direction , to increase the amount of reduced SO₂Cl₂.
Hence, reaction will go in forward direction.
(c)
Removing SO₂ from the system , i.e. decreasing the concentration of SO₂ , according to Le Chatelier , the reaction will move in backward direction , to increase the amount of reduced SO₂.
Hence, reaction will go in backward direction.
