No one can figure out this question! NOT EVEN PAID PH.D ONLINE PROFESSIONALS, PLEASE HELP!?
At a particular temperature 8.0 mol NO2 gas is placed in a 1.0-L container. Over time the NO2 decomposes to NO and O2:
2NO2(g) 2NO(g) + O2(g)
At equilibrium the concentration of NO(g) was found to be 3.8 mol/L. Calculate the value of K for this reaction (using units of mol/L for the concentrations).
