So im studying for the test/final and i came upon a slight confusion. For the Hoff equation, I have two slightly different ones. One of which my TA provided for me and other is from the textbook. The textbook reads lnK2/k1=change in H/R(1/t1-1/t2) and the one my ta derived is lnk2/k1=change in H/R(1/t2-1/t1). Are they the same or is one correct, the other is not? help please and thank you

I think they're both the same. I believe one equation is lnk2/k1=-delta(h)/R(1/t2-1/t1) and the other is lnk2/k1=delta(h)/R(1/t1-1/t2). When you do the math, I believe they work out to be the same things.
