Hello!
please help me!
The nerve gas phosgene decomposes according to COC12(g) - CO(g) + Cl2(g), K = 0.32 at 1000 K. If
the initial concentration of phosgene is 0.015 M. what are the equilibrium concentrations of all gases?

Answer:

[tex][CO]=[Cl_2]=0.01436M[/tex]

[tex][COCl_2]=0.00064M[/tex]

Explanation:

Hello there!

In this case, according to the given chemical reaction at equilibrium, we can set up the equilibrium expression as follows:

[tex]K=\frac{[CO][Cl_2]}{[COCl_2]}[/tex]

Which can be written in terms of x, according to the ICE table:

[tex]0.32=\frac{x^2}{0.015M-x}[/tex]

Thus, we solve for x to obtain that it has a value of 0.01436 M and therefore, the concentrations at equilibrium turn out to be:

[tex][CO]=[Cl_2]=0.01436M[/tex]

[tex][COCl_2]=0.015M-0.01436M=0.00064M[/tex]
