CHEM-C 117 Study Guide - Midterm Guide: Haber Process, Cookie Monster, Molar Concentration
Document Summary
More detail to help understand equilibria conceptually: chemical equilibrium- state where the concentrations of all reactants and products remain constant with time. Concentrations reach levels where rate of forward reaction equals rate of reverse reaction. Has nothing to do with amounts of each product and reactant. On molecular level, there is frantic activity (dynamic, not static situation) In most cases, products revert back to reactants (reverse reaction) and those will react again in ongoing process. In stoichiometry we talk about theoretical yields, and the many reasons actual yields may be lower. Actual yields may be lower because of reversibility of chemical reactions; some reactions may.
