Chemistry Practical: Investigating the Effect of Concentration on Reaction Rate

The video tutorial explains an experiment to investigate how increasing the concentration of a reactant affects the rate of reaction, using the reaction between calcium carbonate and hydrochloric acid. It covers the hypothesis based on collision theory, identifies independent, dependent, and control variables, and outlines the experimental procedure. The video also discusses data analysis, including plotting a graph and drawing conclusions about the proportional relationship between reactant concentration and reaction rate.

Describe the procedure for measuring the volume of carbon dioxide gas collected during the experiment.
