Question

What is the effect of adding more CO2 to the following equilibrium reaction? CO2 + H2O H2CO3
A. More H2CO3 is produced.
B. More H2O is produced.
C. The equilibrium is pushed in the direction of reactants.
D. no change

Answer 1

\[\color{green}{CO_2 + H_2O \leftrightharpoons H_2CO_3}\]
\[\text{Adding }\sf CO_2\text{ creates a stress on the equilibrium system. Use LeChatelier's Principle.}\]

Answer 2

which means there will be exothermic reaction in other words more product (i:e H2CO3) will be formed :)

Answer 3

... rather ... which means that the equilibrium will shift to the right to offset the applied stress.
