The reaction below reaches equilibrium in a closed reaction vessel. What is the effect of adding a small amount of CO2(g)?

2 NaHCO3(s)  ⇌ 

 Na2CO3(s) + CO2(g) + H2O(g)

Hint: Does adding a small amount of CO2(g) have an effect on the value of the reaction quotient?

 There will be net reaction to the right.

 There will be net reaction to the left.

 The equilibrium position is not affected.
