Answer #1

All the parameters will be different for all the reactions, except Keq (equilibrium constant), because Keq depends on substrate's concentration, which will remain same here.

Reactant (R)------------Product (P)

Keq = P/R

Keq depends upon;

  • Mode of representation of the reaction
  • Stichiometry of Reaction
  • Temperature

From the above conditions we can easily observe that Keq does not depend on catalytic enzymes, so it will be same.
