5I.7 7th edition

If Q=1.0 for the reactin N2 + O2 2NO at 25 C will the reaction have a tendency to form products or reactants, or will it be at equilibrium?

How to you find the K value of the equation?

This is an extremely rare case where Q=1, meaning there are exactly as many products as there are reactants. If no K value is given in the problem, try checking the charts in section 5G, which give the equilibrium constants at various temperatures. I don't think the problem would ask you to guess the K value without giving you any concentrations of the products or reactants. Go based off the graph to see if Q> or < K, which will give you the answer to the problem.
