Which would be true about the following reaction? M + N ? Y + Z
A. Adding a catalyst would alter the final concentrations of products and reactants at equilibrium. B. Both: the reaction is reversible and at chemical equilibrium AND increasing the concentration of M will drive the reaction to the left are correct. C. Because the reactants and products are different molecules, this is not a reversible reaction. D. Starting at chemical equilibrium, increasing the concentration of M will transiently increase the rate of formation of Y and Z. E. Starting at chemical equilibrium, decreasing the concentration of M will increase the concentration of Y and Z.
