Imran did an experiment to see how changing the surface area of limestone affected the rate at which
it reacts with hydrochloric acid. He timed how long it
took for the reaction to produce 50 cm3 of carbon
dioxide gas. His results are shownin the picture

a) What was the independent variable in this
experiment?

b) What was the dependent variable in this
