Engage students in a hands-on investigation of reaction rates using this structured and student-friendly chemistry practical exploring how surface area and acid concentration affect the rate of reaction between calcium carbonate and hydrochloric acid. Students measure mass loss over time as carbon dioxide gas is released, then analyse their results using graphs, gradients, and collision theory. This investigation builds strong experimental and data-analysis skills while reinforcing key re
