A group of students investigates the rate of reaction between calcium carbonate chips and dilute hydrochloric acid.
A student suggests four different changes to the experimental setup. Which change would successfully increase the rate of this reaction?
Use a larger delivery tube to connect the flask to the gas syringe.
Use the same volume of hydrochloric acid but at a higher dilution.
Use a larger conical flask to carry out the reaction.
Use the same mass of calcium carbonate but in a finely powdered form.
