Mass balance problem. I'm not seeing what's wrong here.

Hey. So this probably has a straightforward answer, but for some reason I can't seem to see what my problem is. I have everything in the right order for the solve block. But whenever I type in the K.a(e.a,e.b) after given, it tells me somethings up with my function.

There are a lot of annotations to this problem, its just how I like to do it. The real problem is at the bottom half.

if you can't tell, I'm trying to solve for e.a and e.b

Try this:

You have K.a and K.b defined twice, once as a function and once as a variable. Change the name of the ones with Gibbs energy and then change the names in the solve block accordingly. It works then.
