1 joule of work / coulomb of charge transferred J/C = units Ecell = E (cathode) - E (anode) IMPORTANT: if the reaction gets reversed (in order to balance, sometimes it will need to be reversed), the sign of the Ecell must switch, however if it gets multiplied (in order to balance) IT REMAINS THE SAME!! G = negative = k>1 G = positive = k<1 k is close to 1, G is close to zero k is far from 1, G is far from zero oxidation happens, losing electrons

T=100k spontaneous, low temperature, T delta S is small thermodynamically unfavorable G = negative = k>1 G = positive = k<1 k is close to 1, G is close to zero k is far from 1, G is far from zero the energy of a system related to changes in enthalpy and entropy, at a constant temperature. basically implies that the system is at 1 atm and using 1 M solutions.

as temperature goes to zero, entropy approaches a constant value S = entropy G = Gibbs free energy H = heat energy y + z --> Y+ + Z- (G<0) G = negative = k>1 G = positive = k<1 k is close to 1, G is close to zero k is far from 1, G is far from zero

spontaneous at all Temps, delta G <0 1 joule of work / coulomb of charge transferred J/C = units charging = non-spontaneous using = spontaneous delta G = delta H - (T * delta S) gibbs free energy = enthalpy - (temperature times entropy) *note T is in kelvin, not Celsius

how do you calculate Gibbs free energy what is Gibb's free energy galvanic cell vs electrolytic cell galvanic cell vs electrolytic cell
