### Intensive property

Can someone explain why standard reduction potential is an intensive property, versus an extensive property? I'm still confused as to why standard reduction potential is considered a intensive property.

It is not depended on n. That's why it is intensive property.

Isn't it???

### Re: Intensive property

yes. it is mainly an intensive property because it does not depend on the number of reactions occurring. it is a fixed number

### Re: Intensive property

I had the same question. An intensive property is a property that doesn't depend on the physical quantity, like density. You could double a half reaction to balance the electrons, but since the standard reduction potential is constant it does not need to be double. Since 1 volt = 1 joule per coulomb, if the number of moles is doubled, the coulombs are doubled, and so is the number of joules.The doubling doesn't make much of a difference. An extensive property is one in which the physical quantity of the system actually matters, like mass or entropy.

The unit Volt might make you confused.

1Volt=1Joule/Coulomb->similar to other intensive value such as density (g/mL). Standard reduction potential is a fixed value.

Note: this means that if you multiply the half reaction by a constant, you don't multiply E° by the same constant since E° is an intensive property and is always the same - for that specific half reaction.
