Hi all,

I am currently attempting this question: http://screencast.com/t/MwpF2qwn4 .

So I need to plot a graph like it says here: http://screencast.com/t/UDcWOzpcCxGa 

I then end up with this: http://screencast.com/t/N6SlmhUzcAJ

So if I times the gradient by R I should end up with 29.7 Kj mol^-1 but I instead end up with 57.18 * 8.314 = 475  Kj mol^-1 .

Any thoughts on what I could be doing wrong?

Thanks!

I'm sure its probably something simple I'm missing but can't see what.
