CHEM 1A Study Guide - Midterm Guide: Titration, Reaction Quotient, Buffer Solution
Document Summary
Lecture 11: chemical equaions: key idea: chemical reacions involve exchange of ions, atoms, and/or electrons between reacing compounds, wrap-up points: Most reacions involve exchange of ions or transfer of electrons. Balanced chemical equaions show the exact proporion, or the stoichiometry, in which atoms and molecules react. Mole is the macroscopic equivalent of a single atom or molecule: study guide notes, topics for review: Lecture 12: rates of chemical reacions: key idea: reacions occur upon collisions between atoms, ions, or molecules, and diferent substances are generated, wrap-up points: Rates of bimolecular reacions depend on the individual concentraions of all reactants as well as on the temperature, the geometry and eiciency of collisions expressed by the rate constant, k. In the course of a reacion, the reacion rate decreases as the concentraions of the reactants become depleted: study guide notes, topics for review: Lecture 13: reversibility: key idea: most reacions simultaneously proceed in both direcions.
