Lesson details
Lesson outcome
I can represent graphically and explain how the rate of reaction depends on the concentration of one of the reactants.
Show transcript
The changing rate of a chemical reaction can be represented by a graph of volume of gas produced against time.
When reacting excess acid, the same volume of gas is produced for equal amounts of magnesium.
Doubling the concentration doubles the rate of reaction.
The gradient of a rate of reaction graph can be calculated from a tangent drawn at a point on the curve.
