Question

What favours reverse reactions in chemical equilibrium?

Answer 1

Answer:A decrease in temperature will cause the equilibrium to shift to favour the exothermic reaction. Therefore the reverse reaction rate will decrease sharply, and then gradually increase until equilibrium is re-established. The addition of a catalyst will speed up both the forward and reverse reactions.

Answer 2

Define Le Chatelier's principle.

Predict how the change in amounts of substances, temperature, or pressure will affect amounts of reactants and products present at equilibrium
