please answer all parts, and if you not sure keep it for someone else!
For the following reaction, K_c = 255 at 1000 K. CO(g) + CI_2(g) COCI_2(g) You many want to reference (pages 693 - 702) Section 158 while completing this problem. If a reaction mixture initially contains a CO concentration of 0.1530 and a CI_2 concentration of 0.170 at 1000K. What is the equilibrium concentration CO at 1000 K? Express your answer in molarity to three significant figures. What is the equilibrium concentration of CI_2 at 1000 K? Express your answer in molarity to three significant figures. What is the equilibrium concentration of COCI_2 at 1000 K? Express your answer in molarity to three significant figures.Explanation / Answer
CO(g) + Cl2(g) --------------> COCl2(g)
I 0.153 0.17 0
C -x -x +x
E 0.153-x 0.17-x +x
Kc = [COCl2]/[CO][Cl2]
255 = x/(0.153-x)(0.17-x)
255(0.153-x)(0.17-x) = x
x = 0.136
at equilibrium
[CO] = 0.153-x = 0.153-0.136 = 0.017M
[Cl2] = 0.17-x = 0.17-0.136 = 0.034M
[COCL2] = x = 0.136M
