Title: Equilibrium Partial Pressures Question
Post by: biostudent123 on Feb 20, 2014
At 1000 K, Kp = 19.9 for the reaction Fe2O3(s)+3CO(g)⇌2Fe(s)+3CO2(g)

A) What are the equilibrium partial pressures of CO and CO2 if CO is the only gas present initially, at a partial pressure of 0.912atm ?

Pe CO, Pe CO2 = ?

How did you get 0.952moles ? i tried following the sample, but i get far off values

 (3x/3) x0.938^3 / (3-3x/3) x 0.938^3 = 3x/(3-3x)
x=0.952moles

19.9 = 3x/(3-3x)

19.9(3-3x) = 3x

distribute

59.7 - 59.7x = 3x

59.7 = 3x + 59.7x

simplify

59.7 = 62.7x

59.7 / 62.7 = x

0.952

Thank you padre, at first i didnt understand it in this format, i saw the exact same thing but on a PDF file, which made me  visualize the concepts better.
