For the reaction: HNO2 + H2O <==> NO2- + H3O+ under certain conditions, when no NO2- is present initially, the percent dissociation at equilibrium is 2.7%. How will the percent dissociation at equilibrium change if sodium nitrite and nitrous acid are initially added to the solution (assume that the initial concentration of HNO2 is the same in both cases)? A. It will increase. B. It will decrease. C. It will remain the same because concentrations are always the same at equilibriu
