Gibbs free energy for spontaneous reaction
Recall contribution of enthalpy and entropy to spontaneity of change
Spontaneity for different values of
∆H, ∆S, ∆G
Recall thermodynamic relationships
VAT
UG
SHP
Work without compression/expansion
Non-PV work
Max non-PV work at constant TP
Gibbs free energy. Recall formula
Max non-PV work at constant TV
Helmholtz free Energy. Recall formula
Comversion of electrochemical energy to electrical energy, vice versa using ____
Electrochemical cells
Electrochemical cell that uses spontaneous reaction, thus cell potential is positive
Voltaic
Electrochemical cell taht uses a voltage source to drive non spontaneous redox having negative cell potential
Electrolytic cell
Oxidation occurs at
Anode
Reduction occurs at
Cathod
Recall the measure of electrical potential
Note. F has the highest electrical potential (standard red potentials) means very good oxidizing agent
Faraday’s law of electrolysis
First
Second
Mass of substance involved in an electrochemical reaction is directly proportional to currenta applied. Recall formula (mit norma fajardo)
Certain amount of electricity will result to same equivalents in same circuit. Recalm formula
Opposite of resistance. Ability of substance to allow the transport of charges
Conductivity
Recall series, parallel circuit. And ohms law formula
