6N-6O

Question 1

Nernst equation

Answer 1

Ecell = Ecell°-(RT/nF)lnQ

Question 2

How do u find the equilibrium constant in a battery from the standard potential?

Answer 2

lnK=(nFEcell°)/RT

Question 3

What type of chemical reaction would you use for finding the solubility product and why?

Answer 3

Figure out what is the dissolution equation and solve for that k. This is because by definition solubility is off of how much a solid dissolves/disassociates

Question 4

In electrolysis, how do u determine whether oxygen will form from the electrolysis with water or if the byproduct will form from the electrolysis of the impure substance?

Answer 4

Compare their ecell voltages. The potential will tell u which one favors oxidation/reduction

Question 5

How could u figure out how much moles of electrons a process uses from the amps and time the process has occured?

Answer 5

mol e-=I*t/F, where I is in ampere and t is in seconds, f is faradays constant

Question 6

The Gibbs free energy is equivalent to what and why?

Answer 6

Free energy = -nFEcell. This is because in a reversible non expansion process (electrical work), the free energy is equal to the work process. Remember from physics that work is -qdV for electronics, so if dV is ecell, and nF is the charge, then you get that equation
