### 7th Edition - 5G.3 Mistake?

So I noticed that on part B of problem 5G.3 on page 408, the equation has 10 Nitrogen on one side, and 14 on the other. I noticed the rest of the equation is balanced, and that even the answer on the back shows the partial pressure to a power of 7. Is this a mistake with the textbook?

Lavelle has a link on his website that addresses any textbook mistakes, trying checking there

Hi, I had the same question. I checked the link for textbook mistakes and I did not see that problem on there. I thought we always had to balance the equation first? However, I just left it unbalanced because later on questions specify to balance the equation first and 5G.3 did not specify. I don't think that makes it okay, but that was just my way of accepting it.

Personally, I balanced the equation to get in the habit in case Lavelle gives us an unbalanced equation and doesn't ask us to balance it before finding an equilibrium constant. I heard from other students that the chemistry textbooks normally have some mistakes, so I want to say this is probably one of them.
