Question

What is the effect of adding more water to the following equilibrium reaction?

CO2 + H2O --> H2CO3

A The equilibrium is pushed in the direction of reactants.
B More hydrogen carbonate is formed.
C Carbon dioxide concentration increases.
D There is no effect.

Answer 1

Option B is correct More hydrogen carbonate is formed

Step-by-step explanation:

Step 1: Data given

The Principle of Le Chatelier says 'If the concentration of one of the reaction partners changes, the balance will shift to counteract that concentration change.

Step 2: When adding more H2O

For the equation CO2 + H2O --> H2CO3

If the H2O concentration is increased, the system will attempt to undo that change in concentration by shifting the balance to the right, and so the H2CO3 concentration will increase.

Option B is correct More hydrogen carbonate is formed
