And recall that if our cell voltage is positive, that means we have a product favorite reaction. It's spontaneous. And that makes sense because earlier we said if we have a K greater than one, that means we have a favorable reaction. Our reaction favors this going this way. Likewise, if this K is less than one, if it's a zero nine, then this guy, our natural log of a number that's less than one becomes negative. So our e becomes negative.
