Lesson: Reaction Rate Measurements

In this lesson, we will learn how to find the rate of a reaction by plotting the masses or concentrations of reactants or products.

Worksheet: 4 Questions

Q1:

The rate of a reaction can be determined by measuring changes in the physical properties of the reaction mixture. Which of the following parameters is not typically monitored to obtain a measure of reaction rate?

Q2:

What is the formula for calculating the rate of a reaction from the reaction time and the amount of product formed?

Q3:

Shown in the diagram is the experimental apparatus used to identify the end-point of a reaction from changes in turbidity. The average reaction rate is determined by measuring the time taken for the cross to be obscured by the product suspension.

When monitoring changes in turbidity, the cross must be viewed from directly above. How does this approach help to ensure that the experiment is repeatable?
