7th Edition Question 5G.3 B

5G.3 Write the expression for K for each of the following reaction.
4NH(3) + 6NO --> 7N(2) + 6H(2)O
<--
I was checking if the equation was balanced and saw that nitrogen was not. But in the solution manual it has the expression of K using these coefficients.
Answer: K= (P N2) ^7 (PH2O)^6/ (PNH3)^4 (PNO)^6 Does this mean that the equation is balanced correctly? I hope my question is clear. Can someone please explain.

Re: 7th Edition Question 5G.3 B

I noticed that, too. It might just be a solution manual error, but it's not on the list of errors on the class website. Lavelle did mention in class that the equations have to be balanced to get the right answer, so I think it would be safer to balance it. Maybe the 7 in front of the N2 is supposed to be a 5?

Hope this helps!
