For this question, we are asked to balance then write the equilibrium expression Kc for the reactions
For part b, the equation is
 + F_2 (g) -> IF_5)
. I balanced the equation and got
 + 5F_2 (g) -> 2IF_5)
. Then I used the equation in the book,
^(\Delta n_R)(Kc))
, inputted the corresponding elements and solved for Kc. I got
^4([IF_5]^2 / [I_2][F_2]^5)))
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!
