The equilibrium constant, Kc, for the following reaction is 77.5 at 600 K. CO(g) + Cl2(g) COCl2(g) Calculate the equilibrium con

skelet666 [1.2K]

Answer:

[COCl₂] = 0.373 mol·L⁻¹

[CO] = [Cl₂] = 0.069 mol·L⁻¹

Explanation:

The balanced equation is

CO + Cl₂ ⇌ COCl₂

Data:

Kc = 77.5

n(CO₂) = 0.442 mol

n(Cl₂) = 0.442 mol

V = 1.00 L

1. Calculate the initial concentration of CO and Cl₂

$c = \dfrac{\text{0.442 mol}}{\text{1.00 L}} = \text{1.00 mol/L}$

Step 2. Set up an ICE table.

$\begin{array}{ccccccc}\rm \text{CO}& + & \text{Cl$_{2}$} & \, \rightleftharpoons \, & \text{COCl$_{2}$} & & \\0.442 & & 0.442 & & 0 & & \\-x & & -x& & +x & & \\0.442-x & & 0.442 - x & & x & &\\\end{array}\\$

Step 3. Calculate the equilibrium concentrations

$K_{\text{c}} = \dfrac{\text{[COCl$_{2}$]}}{\text{[CO][Cl$_2$]}} = \dfrac{x}{(0.442 - x)^{2}} = 77.5\\\begin{array}{rcl}\\\dfrac{x}{(0.442 - x)^{2}} & = & 77.5\\\\x & = & 77.5(0.442 - x)^{2}\\x & = & 77.5(0.1954 - 0.884x + x^{2}\\x & = & 15.14 - 68.51x + 77.5x^{2}\\77.5x^{2} - 69.51x + 15.14 & = & 0\\x & = & \mathbf{0.373}\\\end{array}$

[COCl₂] = x mol·L⁻¹ = 0.373 mol·L⁻¹

[CO] = [Cl₂] = (0.442 - 0.373) mol·L⁻¹ = 0.069 mol·L⁻¹
