Problem P19D.7

(Continues from Problem P16D.6) Now suppose that the overpotential is in the high overpotential region at all times even though it is oscillating, and that it takes the form of a sawtooth between varying linearly between $$\eta_{-}$$ and $$\eta_{+}$$ around an average of $$\eta_{0}$$, but in such a way that $$\eta$$ is always positive. Derive an expression for the variation in the current density across the interface; take $$\alpha=\frac{1}{2}$$ .

Chapter 5: Thermochemistry Week 8 10/6/16 Chapter 5: Thermochemistry Part 2: Energy Basics 5.1 – Energy Basics Thermochemistry – the study of measuring the amount of heat (energy) absorbed or released during a chemical reaction or physical change Energy – the capacity to supply heat or do work Work (w) – the process of causing matter to move against an opposing force Potential Energy – the energy an object has because of its relative position, composition, or condition Ex. – An object on the edge of the table versus one on the floor Kinetic Energy – the energy an object possesses because of its motion Ex. – A toy car rolling down a hill as opposed to one already stopped at the bottom Thermal Energy – kinetic energy associated with the random motion of atoms and molecules Temperature – a quantitative measure of “hot” or “cold” Higher average kinetic energy = higher temperature *FLASHBACK Extensive Property – properties that do depends on the amount of matter present Temperature Intensive Property – properties that do not depend on the amount of matter present Thermal Energy Heat (q) – the transfer of thermal energy between two bodies at room temperatures aka “heat flow” *** Thermal energy naturally flows from objects with high temperature to object with low temperature Exothermic Process – any chemical or physical process that releases heat – “feels hot” Endothermic Process – any chemical or physical pro
