QUESTION 5 Consider the following reaction at equilibrium. What effect will adding some C have on the system? CO2(g)+C(graphite) 2 CO(g) The equilibrium constant will decrease. O No effect will be observed since C is not included in the equilibrium expression. O The reaction will shift to the right in the direction of products. O The equilibrium constant will increase. The reaction will shift to the left in the direction of reactants.

Solution

Keeping in mind the Le Chatlier\'s principle ( means when a system experiences a disturbance it will respond to restore a new equilibrium state), in the above reaction, addition of \"C\" make the reaction forward. Hence third option (the reaction will shift to the right in the direction of products) is the correct answer.
