What is the answer for this

Question

What direction would the equilibrium shift if CO2(aq) was added to this reaction at equilibrium?

H2CO3(aq)    <------->      CO2(aq) + H2O(l)

Answer 1

Since you are adding more product (CO2), you would have an excessive product. To reduce this stress, you would shift the equilibrium to the left (toward the reactants) to make more reactants.
