2014 Midterm Question 5C

Postby Jason Zhang 2B » Sat Feb 06, 2016 10:01 pm

On the 2014 practice midterm, question 5C asks to identify various functions as either state functions or path functions. I was wondering why E (which I assume is cell potential) is considered a path function?

I believe this may be a mistake. E is used for internal energy, which is a state function because it can added or subtracted. I'm pretty sure work and heat are the only non-state functions.

E is not a state function: see this question
