Rates of Reactions - Part 1

The video explains the concept of reaction rate, which measures how quickly reactants turn into products. It describes two methods to measure reaction rate: by observing the decrease in reactants or the increase in products. Examples include a reaction between calcium carbonate and hydrochloric acid, where the decrease in mass of reactants or the increase in volume of carbon dioxide is measured. Graphs are used to analyze the rate of reaction, showing that it typically decreases over time. The video concludes with a recap of these concepts.

Describe the first method of measuring reaction rate using reactants.

What is the significance of the gradient in the reaction rate graph?
