Answer:
Explanation:
Hello,
In this case, for the given reaction, the equilibrium expression is:
That in terms of the reaction extent is written as (initial concentration of NO2 is 0.24 M for 0.24 mol in 1.00 L):
Moreover, since at the equilibrium 0.14 moles of NO are present (a 0.14-M concentration), we can compute the reaction extent as shown below:
In such a way, knowing , we compute Kc as shown below:
Regards.
Explanation:
elements are carbons and hydrogen
This sounds like paper chromatography. Let me know in the comments if the answer is something else.
