Vinegar (acetic acid) in a solution will react with chalk (calcium carbonate) a solid. the rate of the reaction can be determined by how quickly carbon dioxide, one of the products, is produced. which solution of acetic acid will produce the highest reaction rate?

The more concentrated the solution of acetic acid, the highest the reaction rate. Thus, 12M acetic acid will react faster than 5M acetic acid. The more the amount of acetic acid solution, the highest the reaction rate. Increasing the temperature of acetic acid solution also increases the rate of reaction between acetic acid and calcium carbonate.
