Module 5 Overview & Instructions

PRT 1220Equilibrium

Foreword

This week, we focus on solving problems involving chemical systems at equilibrium and proceeding toward equilibrium.  At the end of the week, we'll review some basics of drawing structures for molecular compounds, which will help us acid-base concepts, our next major topic.

Questions and Answers

Whatever you're struggling with this week, somebody else in our section probably is struggling with it, too.  Post your question on the Module 5 Q&A Board.

If you know the answer to someone's question, post it.  It's almost a certainty that more people in our section than just the person who posted the question want to know the answer.

Learning Outcomes/Objectives

By the conclusion of this learning module, you should be able to:

• draw and use an ICE table for chemical reactions in solving equilibrium problems.
• use a balanced reaction and its equilibrium constant to solve for equilibrium concentrations and/or pressures.
• calculate Q for a reaction not at equilibrium and predict which way the reaction will proceed.
• use Le Chatelier's Principle, both qualitatively and quantitatively, to predict the direction a reaction will proceed to reestablish equilibrium after a disturbance.
• calculate a new equilibrium position following a disturbance to a system previously at equilibrium.
• understand, especially through the Haber-Bosch process, the effects of temperature and catalysis on rate and equilibrium.
• draw Lewis structures.
• draw skeletal structures for compounds containing carbon chains.
• determine the molecular formula of a compound from its skeletal structure.
• draw multiple isomers of a given molecular formula.
• identify alkanes, alkenes, and alkynes.
• determine the number of sites of unsaturation in an organic molecule.
