Rate of Reaction


The Rate of Reaction

Understanding the rate of reaction is very important in Pūtaiao we need to be able to control it when performing reactions on an industrial scale.

It can be defined as the rate at which products are produced OR reactants are used up.



Here are two ways we can measure the rate of reaction:

Can you think of any others?

Whakamātau: Measuring the Rate of Reaction

Method is on Google Classroom


Production of Gas Method

When measuring the amount of gas produced, the volume goes up over time so the graph should look like this:

{width=50%}


Loss of Mass Method

When measuring the amount of mass lost, the mass goes down so the graph should look like this:

{width=75%}
