Consider the reaction N₂O4 (g) - NO2 (g) where Kc = 0.20 at 25 °C. If 0.40 mol NO₂ and 0.80 mol N₂04 are introduced into a 1.0 L flask at 25 °C, what change in concentrations (if any) will occur in time? A. [NO₂] will decrease and [N₂04] will decrease. B. [NO₂] will increase and [N₂04] will decrease. C. [NO₂] will increase and [N204] remain unchanged. D. [NO₂] will decrease and [N₂04] will increase. E. [NO₂] and [N2O4] remain unchanged.
