A chemistry student wants to determine the effect of adding more reactant or product on the equilibrium position of a chemical reaction. The student has a 0.50 M solution of N2O4 and NO2 at equilibrium at 25°C, with the equation N2O4(g) <--> 2NO2(g). If the student adds more N2O4 to the reaction mixture, what will happen to the equilibrium concentration of NO2? Will it increase, decrease or stay the same? Justify your answer with a chemical equation and relevant calculations.
