Please see attached picture.
I need verification of my answers. I unfortunately found these problems on an old book with no answer. I would really appreciate it.

(a) Ok. For this one, I am really not sure. PLEASE help.
I get a very complicated formula.

(1+x)(x^4)/(1-x)^2=Kp.

Now, this makes no sense because I am not able to solve more than quadratics. This book should represent problems I could see on exams where they do not expect me to do more than quadratics. What do I do?

(b) DG=DGnaught+RTln(Q)
Q=Kp so DG=0.
DGnaught=28058J
DGnaught=DH-TDS.
DS=258mol/K.

(c) Reaction is endothermic. Adding temperature will make reaction go forward more.

hm i think Kp should be 

$K_p=\dfrac{(1+x)(4x)^2}{(1-2x)^2}$

aaronq · Answer

but maybe since Kp is so small you ignore x from the bottom term?

Perfect.
