Fundamental Equilibrium Concepts
... Imagine a beach populated with sunbathers and swimmers. As those basking in the sun get too hot and want to cool off, they head into the surf to swim. As the swimmers tire, they head to the beach to rest. If these two rates of transfer (sunbathers entering the water, swimmers leaving the water) are ...

... is 0.113 at 298 K, which corresponds to a standard free-energy change of 5.4 kJ/mol. In a certain experiment, the initial pressures are PN2O4 = 0.453 atm and PNO2 = 0.122 atm. Calculate ΔG for the reaction at these pressures, and predict the direction in which the reaction will proceed spontaneously ...

Overview of Reference Electrodes and Alternative
... For an electrode reaction to occur within an electrochemical cell, there must be at least two electrodes; the working electrode facilitates electron transfer to the analyte of interest while the counter electrode maintains electroneutrality by participating in a reaction of opposite sign. Though it ...
