Kc for the following reaction at 25C is 4.8x10-6. Calculate the equilibrium concentration (in mol/L) of Cl2 (g) if the initial concentration of ICl (g) is 1.33 mol/L. There is no I2 or Cl2 initially present.

2ICl(g)=I2(g)+Cl2(g)

 

Thanks in advance.

i get 2.91x10-3 , but not too sure, didn't have time to check working properly

It's correct.

 

Lifeisogood : How will you tackle this problem ?

 

There are two tools at your disposal :

 

(i) The ability to write and balance the required equation and infer stoichiometric proportions from it;

(ii) the definition for Kc

 

Write down what these two tools give you, and if you're still stuck, we'll help you out.
