Spontaneous Reduction

Postby Aarthi_Lakshmi_2A » Sun Feb 05, 2017 11:41 pm

How does a positive standard reduction potential indicate that reduction is spontaneous? Is there a specific reason? And if the standard reduction potential is negative, does that mean oxidation is spontaneous?

It is summed up very well in the course reader on page 49, but essentially we know that deltaGo=-nFEo, and from the previous chapter, when deltaG is negative, the reaction is spontaneous, which means that Eo is always positive when deltaG is negative.
