When you add baking soda to vinegar, the mixture fizzes as carbon dioxide gas is produced. Suppose you added water to vinegar before you mixed it with the baking soda. Why will the rate of carbon dioxide production decrease?

because the water would diloute the chemicals in the vinegar

Explanation:

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
