Lesson 2

Module 8—Acid-Base Equilibrium

Reflect on the Big Picture

 

Think back to the Module 8 Big Picture, which discussed examples of equilibrium in the soil, water, and atmosphere.

 

The combustion process that occurs in automobile engines and furnaces produces nitrous oxides, NO(g) and NO2(g). The following unbalanced series of reactions describes the deposition of nitric acid as a result of the chemical joining of nitrogen and oxygen that occurs during a combustion reaction.

 

     N2(g) + O2(g) + 180 kJ 2 NO NO2(g) HNO3(g) → deposition

 

Use your knowledge of equilibrium to explain how the energy from high-temperature combustion processes contributes to the production of HNO3(g).

 

Save a copy of your response in your course folder. You will further evaluate your answer later in this module.

 

Reflect and Connect

 

In Lesson 1 you initiated a summary about the strength of acids and bases. Take this opportunity to update your summary to include concepts you learned in this lesson. Save a copy of your updated summary in your course folder. You may be asked to submit a copy of this summary to your teacher for feedback.
