Comment on the changes in the concentrations of SO2 O2 and SO3 at equilibrium if we were to make the following changes. (Select all that apply.)(c) increasing SO2 concentration1.It will lead to an increase of O2.2.It will lead to an decrease in the concentration of SO3.3.It will lead to a decrease in the concentration of O2.4.It will lead to an increase in the concentration of SO3.(d) adding a catalyst1.It has no effect on the position of the equilibrium.2.The equilibrium will shift to the right.3.The equilibrium will shift to the left.(e) adding helium at constant volume1.It has no effect on the position of the equilibrium.2.The equilibrium will shift to the right.3.The equilibrium will shift to the left.
