CHEM 112 Study Guide - Gas Constant, Solubility Equilibrium, Spectator Ion
Document Summary
For the reaction in gas phase, , and thus is the change in gibb"s free. R is the ideal gas law constant, 8. 314. K is the equilibrium constant is the stoichiometric difference between products and reactants. A chemical equilibrium displays all of the following characteristics: The system shows no macroscopic evidence of change. Equilibrium is reached through a spontaneous reaction. A dynamic balance of forward and reverse reactions exists. When temperature is constant, the same equilibrium constant will be obtained, regardless of the direction from which it was approached. When k is large, almost 100% of limiting reagent is consumed and thus the reaction is considered to go to completion. Similarly, when k is very small, the reaction is considered not go at all. Reactions involving substances such as acid/base reactions or redox reactions. Relationship of k" to the balanced chemical reaction. Multiplying by coefficients by a common factor raises k to that common factor.
