Use line notation to represent each electrochemical cell

Chapter 7 Continued 1. Thermodynamics (in first set of ntoes) 2. Experimental Determination of Energy Change in Reactions (in first set of notes) 3. Kinetics (in first set of notes) 4. Equilibrium a. Rate and Reversibility i. Equilibrium reactions are chemical reactions that do not go to completion. AKA all reactants do not convert to products. Also known as incomplete reactions. b. Physical Equilibrium i. Reversible reactions. SO they can occur in either direction (products to reactants or reactants to products) ii. Represented by double arrows, one facing each way 1. Double arrow serves as an indicator for a reversible process, an equilibrium process, or the dynamic nature of a process iii. Dynamic Equilibrium­ when the rate of the forward process of the reaction is exactly equal to the rate of the backward process. 1. Rate soluterate settles 2. Ex. Sugar (s)sugar(aq) = sugar (aq) sugar (s) iv. Chemical Equilibrium 1. As a reaction begins, its forward reaction rate is quick, but as time goes on that rate decreases. a. To start­ [reactants] are high and [products] is low
