At the equilibrium, the concentration of products equal to the concentration of reactants. *
A dynamic equilibrium means rates of forward and reverse reactions are equal. *
An equilibrium constant with a value K > 1 means: *
the reaction is not at equilibrium
there are more products than reactants at equilibrium
there are the same amount of products and reactants at equilibrium
there are more reactants than products at equilibrium
The equilibrium constant for the reaction H2(g) + I2(g) ↔ 2 HI(g) *
K = [H2][I2]/[HI]^2
K = [H2][I2]/2[HI]
K = 2[HI]/[H2][I2]
K = [HI]^2/[H2][I2]
The equilibrium constant for the reaction SnO2 (s) + 2 H2 (g) ↔ Sn (s) + 2 H2O (g) *
K = [H2O]^2/[H2]^2
K = [Sn][H2O]^2/[SnO][H2]^2
K = [H2]^2/[H2O]^2
K = [SnO][H2]^2/[Sn][H2O]^2
For the reaction N2 (g) + 3 H2 (g) ↔ 2 NH3 (g), if hydrogen gas is added after the reaction has reached equilibrium, the reaction will: *
shift to the right to produce more product
stop. All the nitrogen gas has already been used up.
shift to the left to produce more reactants
For the reaction N2 (g) + 3 H2 (g) ↔ 2 NH3 (g), if the volume of the container is decreased the reaction will: *
shift to the right to produce more product
no shift to left or right
shift to the left to produce more reactants
For a reaction at equilibrium whose H is -512 kJ, heating this reaction will... *
shift the reaction to the left
shift the reaction to the right
