### Question 11.39

"Use the information in Table 11.2 (pg. 428) to determine the value of K at 300 K for the reaction 2 BrCl (g) + H2 (g) <--> Br2 (g) + 2 HCl (g)."

I understand the concept of the question and what it is asking, but I am not sure how to solve it and why that would be the answer. If someone could please explain this to me, that would be great! Thank you in advance!

Well you are given this equation at 300 K and as you can see the equation you're given is two equations on the chart 11.2 combined. You can say that they are multiplied into one equation so you would look at both these equations on the chart at 300 and multiply their Kc.

wouldn't we add the Kc values? I'm also having trouble with this problem and I'm not quite sure which two base equations to look at, from the chart.

Look at the base equations H2 + Cl2= 2HCl and 2BrCl=Br2 = Cl2 which have corresponding K values and multiply those K values together.
