Change Made to a Reaction
that was at Equilibrium:
Increase the concentration of a reactant.
Increase the concentration of a product.
Decrease the concentration of a reactant.
Decrease the concentration of a product.
Response:
Rate of the forward reaction becomes greater than the rate
of the reverse reaction until equilibrium is reestablished.
Rate of the reverse reaction becomes greater than the rate
of the forward reaction until equilibrium is reestablished.
Rate of the forward reaction becomes less than the rate of
the reverse reaction until equilibrium is reestablished.
Rate of the reverse reaction becomes less than the rate of
the forward reaction until equilibrium is reestablished.
