Lesson: Measuring Enthalpy Changes

Chemistry

In this lesson, we will learn how to perform calorimetry experiments and use the results to calculate the enthalpy change for a chemical reaction.

Worksheet: 14 Questions

Q1:

The diagram below shows the experimental setup for a simple calorimeter to measure the enthalpy change in certain reactions. For which type of reaction would this experimental apparatus not be suitable for measuring the change in enthalpy?

Q2:

Which of the following statements best describes what calorimetry is?

Q3:

The diagram below shows the experimental apparatus for a combustion calorimeter.

Why is a copper container used in this calorimeter?

Why is the experimental apparatus surrounded by draught excluders?
