Investigating the Effect of Concentration on Chemical Reaction Rate: A Practical Experiment

In this video, the speaker discusses a required practical activity on the chemistry specification which involves investigating how increasing the concentration of a reactant increases the rate of reaction by collecting a gas. The speaker explains collision theory and its relevance to this experiment. The hypothesis is presented and the reaction to be used to test the hypothesis is highlighted. The dependent and independent variables are identified, as well as the control variables. The equipment required for the experiment is presented, as well as the steps involved in conducting the experiment. The speaker explains how to calculate the rates of reaction and how to plot the results on a graph. The conclusion is drawn based on the results of the experiment.
