Hi! I need assistance with calculating the equilibrium constant of an overall reaction, yet whatever I try does not work.
The overall reaction is
2Cl₂(g) + 10 NO(g) <-> 5N₂(g) + 2Cl₂O₅(g)     with K_p=?

I am given:
2Cl₂O₅(g) <-> 5O₂(g) + 2Cl₂(g)    K_p1 =.095
2NO(g) <-> N₂(g) + O₂(g)      K_p2 =476

So I reversed the first equation given, thus I invert the respective equilibrium constant to get 1/.095; then I noticed that the overall reaction has 10 NO, thus I multiply the second given equation by 5, this requires me taking the equilibrium constant raised to the 5th power, thus I have 476⁵. Lastly, since I am adding the two equations together, I multiply the two equilibrium constants to get my overall equilibrium constant, which should be (476⁵)/(.095) however this is incorrect; what is my error?

Why do you think what you got is incorrect?

It looks OK to me.

My homework system (Canvas) keeps saying it is incorrect, I've tried entering the number in scientific notation (2.57 x 10¹⁴), tried typing out the actual number, yet it will not accept this value. I've checked with a few friends and they are also stuck on the same problem, we got the same answers.

I doubt about K_p1 =.095. Cl₂O₅ is absolutely exotic, I doubt one obtains so much in an equilibrium mixture of O₂ and Cl₂.

All I can tell is that I don't see anything wrong with your approach and the result looks OK (in terms of the data given).

Ah it was an error by my professor! He updated the class that he forgot to input an answer when setting up the assignment, so the assignment defaulted to the answer of 0. Just updating here!
