Trying to figure out this equation I did the first part but I am really having trouble getting this one and my professor told me to re do it. Trying to calculate ke for the following equation (equilibrium concentration below problem)

NO^2(g) + O^2(g) + heat <-> NO(g) + O^3(g)
[0.072] [0.083] [6.73 X 10^-2] [6.73 X 10^-2]

I would like to see your calcs

I am not certain what the second lines means,

On your first line, ^ is a symbol that I don't understand. I assume you mean subscript.

IF that is so, then Ke

= (6.73)^2 /((.072)(.083)) *10-4
