### Help on 11.9: b and c

Posted:

**Mon Jan 07, 2019 2:54 pm**For this question, we are asked to balance then write the equilibrium expression Kc for the reactions

For part b, the equation is . I balanced the equation and got . Then I used the equation in the book, , inputted the corresponding elements and solved for Kc. I got

for my answer, but in the back of the book, there's no (RT)^4 in front. Everything else was correct, but I am unsure why there's no RT in the answer. Is there another way I am supposed to solve this?

Thanks!
