Yield of reactions

Dynamic equilibrium is a fundamental concept in chemistry that enables chemists to increase the yield of chemical reactions by manipulating factors such as temperature, pressure, and concentration. An important principle in predicting the effects of these changes to chemical equilibrium systems is Le Chatelier’s principle. This will be used to qualitatively examine equilibrium systems and the factors that affect them. Equilibrium will also be explored quantitatively using equilibrium expressions, reaction quotients and concentration-time graphs. Chemists have to navigate the compromise between reaction conditions that optimise the rate of reaction with conditions that optimise the yield of reactions.

This resource revises yield of reactions and within yield of reactions there are 4 key concepts:

• dynamic equilibrium
• the equilibrium law
• Le Chatelier’s principle
• application of equilibrium concepts.

To determine if this resource will benefit you, start by answering the following questions:

• How can chemists make chemical products efficiently?
• How can they minimise the amount of waste?
• How can they reduce the energy cost of making new chemicals?

The answers to these questions are provided on the following pages. Use this resource to refresh your memory, reinforce your understanding of these concepts, and prepare more effectively for university-level learning.
