CHEM 112 Study Guide - Gas Constant, Solubility Equilibrium, Spectator Ion
Document Summary
For the reaction as follows: aa+bb +hh , k c=[g]g[h ]h. For the reaction in gas phase, 2so2 (g)+o2(g) 2 so3(g) Px=[ x ] rt and thus k p=k c(rt ) n. )2 (p so2)2(po2 is the change in gibb"s free. R is the ideal gas law constant, 8. 314. N is the stoichiometric difference between products and reactants. 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. Types of equilibrium systems: homogenous gas phase systems, heterogenous mixtures of solid/gas, solid/aqueous, aqueous/gas, reactions involving substances such as acid/base reactions or redox reactions. Relationship of k" to the balanced chemical reaction. Inverting the bce causes inversion of k: multiplying by coefficients by a common factor raises k to that common factor, dividing coefficients by a common factor causes k to be taken to that factor"s root.
