110. Polychlorinated biphenyls (PCBs) have been used extensively as dielectric materiàls in clectrical transformers. Because PCBs have been shown to be potentially harmful, analysis for their presence in the environment has become very important. PCBs are manufactured according to the following generic reaction: This reaction results in a mixture of PCB products. The mixture is analyzed by decomposing the PCBs...

Use the reaction quotient, Q, to explain why the fraction of dissociation of weak acid, HA, increases when the solution is diluted by a factor of 4. When the system is at equilibrium, Q = [A^-][H^+]/[HA] = K_a. Let's call the concentrations at equilibrium [A^-]e, [H^+]e, and [HA]_e. if the solution is diluted by a factor of 4, the concentrations...
