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)Starting at chemical equilibrium,increasing the concentration of M will transiently increase the rate of formation of Y and Z.
C)Starting at chemical equilibrium,decreasing the concentration of M will increase the concentration of Y and Z.
D)Both: the reaction is reversible and at chemical equilibrium AND increasing the concentration of M will drive the reaction to the left are correct.
E)Because the reactants and products are different molecules,this is not a reversible reaction.

B) Starting at chemical equilibrium, increasing the concentration of M will transiently increase the rate of formation of Y and Z. This is consistent with Le Chatelier's principle, which states that a change in the conditions of a reaction at equilibrium will cause the system to adjust in a way that counteracts that change. Adding more of a reactant (in this case, M) will temporarily increase the rate at which products (Y and Z) are formed, as the system seeks a new equilibrium position.
