Q.1
CS2(g) + 3Cl2(g) ------------------ S2Cl2(g) + CCl4(g)
The reaction is exotherrmic.
According to Lechatelier principle , the exothermic reactions are favoured at low temperatures. so when the temperatures is increase means endothemic reaction is favoured. ,i, e back word is favoured.
Hence in the backword reaction , the amout of CCl4 is decreses.
The answer is 2.
Q.2
The naswer is 5.
At equilibrium postion also the reaction is continuously takes place.
Q3.
The answer is 3.
Argon is inert medium. so there is change in presence of inert medium on equilibrium.
Q4.
CS2(g) + 3Cl2(g) ------------------ S2Cl2(g) + CCl4(g)
when volume of the contained is decreased then the equilibrium adjusted to the number moles decresed side.
In the above reaction number of moles decresed to the forword direction ( 1+3------------ 1+1).
so the volume is decreased the forword reaction is favoured. i,e the amount of CCl4 is increased.
The answer is 1.
Q5
The equilibrium constnat depends only on temperature.
The answer is 3.
Q.6
CS2(g) + 3Cl2(g) ------------------ S2Cl2(g) + CCl4(g)
when CS2 is added to the system, the concentration of the reactants are increases. The increased amout of CS2 is decresed to the direction of forword direction . ,i,e forword reaction is favoured.
so the amout of CCl4 is increased.
The answer is 1.
Q.7
There is no effect of catalyst on equilibrium conditon .
The answer is 3.
