We're being asked to identify the statement that is true for all equilibrium systems.
When a reaction is in equilibrium, reactants do not completely convert into products. The reaction moves in the forward and in the reverse direction.
Which statement is true for all equilibrium systems?
A. The mass of the reactants is equal to the mass of the products.
B. The addition of a catalyst changes the equilibrium concentrations.
C. The concentration of the reactants is equal to the concentration of the products.
D. Heating the system always favors the exothermic reaction.
E. The rate of the forward reaction is equal to the rate of the reverse reaction.
