Decide which of the following statements are True and which are False about equilibrium systems:
If K = 8 for the reaction A + B ⇌ C + D, K will equal -8 for the reaction C + D ⇌ A + B
For a reaction with K >> 1, the rate of the forward reaction is less than the rate of the reverse reaction at equilibrium.
The value of K at constant temperature does not depend on the amounts of reactants and products that are mixed together initially.
A large value of K means the equilibrium position lies far to the left and that a lot of reactant will be present at equilibrium
(1)
False
If K = 8 for the reaction A + B ⇌ C + D, K will equal to 1/8 for the reaction C + D ⇌ A + B.When we reverse a chemical equation, the value of the equilibrium constant for the new equation will be the reciprocal of the value of the equilibrium constant of the old equation.
(2)
False
For a reaction with K >> 1, the rate of the forward reaction is more than the rate of the reverse reaction at equilibrium.
(3)
True
The value of K at constant temperature does not depend on the amounts of reactants and products that are mixed together initially.
At constant temperature, the value of the equilibrium constant K is constant.
(4)
False
A large value of K means the equilibrium position lies far to the right and that a lot of product will be present at equilibrium
A small value of K means the equilibrium position lies far to the left and that a lot of reactant will be present at equilibrium
