The change in pressure is based on the gas produced during the reaction. Evaluate the claims, evidence, and reasoning behind currently accepted explanations or solutions to determine the merits of arguments. Construct and revise an explanation based on valid and reliable evidence obtained from a variety of sources (including students' own investigations, models, theories, simulations, peer review) and the assumption that theories and laws that describe the natural world operate today as they did in the past and will continue to do so in the future. Could you just keep adding more and more baking soda to the same amount of vinegar to get more carbon dioxide? There's the reason for the 3:1 ratio of moles of sodium bicarbonate and citric acid!
