standard potential of a redox reaction

Postby 405318478 » Tue Feb 25, 2020 11:41 am

Suppose I am balancing a redox reaction, and need to multiply one of the half reactions by some coefficient. Would the E for that half reaction also be multiplied by the same coefficient?

I have written down that standard energy potential is an intensive property and so it doesn't depend on how many times the reaction occurs, it is always the same. However, reaction potentials are only given for reduction reactions so if your half reaction is an oxidation then you must flip the sign of the standard energy potential.

E Is an intensive property, so you do not multiply the E value when the equation is multiplied.

Because E is intensive it does not rely on the amount products or reactants present, so you would NOT multiply the E value. The only time you alter the E value is when you flip the equation; then you would multiply it my -1.
