Lesson: Choosing Equilibrium Conditions Chemistry • 10th Grade

In this lesson, we will learn how to predict the effect of changing the temperature, concentration, or pressure on the yield of industrial reactions and its financial consequences.

Lesson Plan

Students will be able to

evaluate combined changes in concentration, pressure, and/or temperature on the position of an equilibrium,
explain how decisions regarding reaction conditions relate to fixed and long-term costs and yield,
apply knowledge of equilibria to suggest conditions for common industrial processes.

Q1:

Hydrogen can be produced using methane and steam and the forward reaction is endothermic, as shown: Which of the following changes in conditions would cause no change in the equilibrium yield but increase the rate of reaction?

Q2:

The production of methanol is a reversible reaction and the forward reaction is exothermic. Consider the following reaction: Which of the following changes in conditions would cause a decrease in the equilibrium yield but an increase in the rate of reaction?

Q3:

The contact process, illustrated in the diagram, is a step in the production of sulfuric acid:

Which of the following statements about altering the temperature is true?
