And if it's not at equilibrium, the reaction quotient can be used to determine if the reaction will proceed to the right (forming more products) or to the left (forming more reactants). He works two examples and gives students a helpful mnemonic aid to remember the direction in which equilibrium will proceed. 00:00 Introduction 00:34 What Is the Reaction Quotient? 03:25 A Mnemonic Aid 04:22 Example Number 2 06:23 Conclusion
