CHM 2046 Chapter Notes - Chapter 12: Dynamic Equilibrium, Supersaturation, Ideal Solution
Document Summary
Chemistry chapter 12: 12. 1, solution: a homogeneous mixture of 2 or more substances or components. Entropy: measure of energy randomization or energy dispersal in a system. The pervasisve tendency for energy to spead out/disperse whenever it"s not restrained from doing so is the reason that 2 ideal gasses mix: the effect of imfs. Solvent-solute interactions: interactions between a solvent particle and a solute particle. Solvent-solvent interactions: interactions between a solcent particle and another solvent particle. Solue-solute interactions: interactions between a solute particle and another solute particle. Miscible: two substances that are soluble in each other in all proportions. D. v: 12. 3 energetics of solution formation, steps in energy changes: Separating solvent particles to make room for solute particles: endothermic. Mixing the solute particles with the solvent particles: exotherminc: hsoln= hsolute+ hsolvent+ hmix (solute/solvent are +, mix is -, the sign of hsoln depends on the magnitudes of individual terms.
