What is the effect of adding more water to the following equilibrium reaction? #CO_2 + H_2O rightleftharpoons H_2CO_3#?
adding more water will drive the reaction towards the products.
Increasing the reactants ( water) will drive the reaction toward the product (s) In this case Carbonic acid.
Increasing Carbon Dioxide will also drive the reaction toward the product(s) This is one reason why increased production of Carbon Dioxide has not resulted in the predicted increase in global warming. The Carbon Dioxide dissolves into the Ocean and lakes removing the Carbon Dioxide from the atmosphere.
