Answer from: dayanirisr45

The correct option is, Adding more of gas C to the system.

Explanation :

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

For the given equation :

$A(g)+B(s)+Energy\leftrightharpoons 3C(g)$

This is a type of Endothermic reaction because heat is absorbed in the reaction.

For the given options :

Option A: Adding more of gas C to the system

If the concentration of gas C that is the product is increased, so according to the Le-Chatlier's principle, the equilibrium will shift in the direction where decrease of concentration takes place. Therefore, the equilibrium will shift in the left direction.

Option B: Heating the system

If the temperature is increased, so according to the Le-Chatlier's principle , the equilibrium will shift in the direction where increase in temperature occurs. As, this is an endothermic reaction, forward reaction will decrease the temperature. Hence, the equilibrium will shift in the right direction.

Option C: Increase the volume

If the volume of the container is increased, the pressure will decrease according to Boyle's Law. Now, according to the Le-Chatlier's principle, the equilibrium will shift in the direction where increase in pressure is taking place. As the number of moles of gas molecules is greater at the product side. So, the equilibrium will shift in the right direction.

Option D: Removing some of gas C from the system

If the concentration of gas C that is the product is decreased, so according to the Le-Chatlier's principle, the equilibrium will shift in the direction where decrease of concentration takes place. Therefore, the equilibrium will shift in the right direction.

Hence, the correct option is, Adding more of gas C to the system.
