a) What is the value of the reaction quotient (Qc ) for the reaction below if a 2.75-L flask contains 0.0282 mol NO2(g) and 0.612 mol N2O4(g) at 25°C?
N2O4(g) ? 2 NO2(g), Kc = 4.61x10-3 at 25°C
Enter your answer with 3 significant digits.
(b) If the reaction is not at equilibrium, in which direction will the reaction proceed-toward products or reactants?
