Re: Determining n
n is the number of electrons being transferred in the reaction. When you balance both half reactions you can find the value of n.

Re: Nerst Equation
In a review session, one of the TAs said lavelle would never ask us to derive an equation.

Re: Oxidation vs Reduction Half Rxn
I always use LEO says GER. Losing Electron = Oxidation. Gaining Electron=Reduction.

Re: Instantaneous vs Average
Average Rate of change is the rate over a period of time. Instantaneous rate of change is the rate at a specific time t.

Re: oxidizing agent and reducing agent
The oxidizing agent is whats being reduced. and the reducing agent is whats being oxidized. You know if its being oxidized if it is becoming more negatively charged, and reduced if it is getting positively charged.

Re: Creating a cell diagram
you do not need to include H20 only H+ and OH-

Re: Adding H+ and H2O
remember that acidic and basic solutions, you add different molecules!!!

Re: Test
Anything after thermodynamics. Except Gibbs free. It should mainly focus on that and electrochem.

Re: Cell diagram
I think traditionally the anode is on the left, and the cathode is on the right.

Re: Test #2
Gibbs free energy, mainly because I dont know which equations to use in which situation. Dr.Lavelle gave us a lot to work with so its a little more confusing than some of the electrochem stuff we've been looking at.

Re: State Properties
work and Heat are not considered state properties because they are dependent on the path taken.

Re: Why are phase changes endothermic?
Phase changes are endothermic because of the heat released from bonds breaking.
