a) False
Chemical equilibria are dynamic. At equilibrium, both the forward and reverse reactions occurs, and their rates are equal.
b) False
At equilibrium, the total moles of products and the remaining moles of reactants are determined by the initial number of moles, the equilibrium constant and the volume of the system. No such conclusion can be made.
c) True
This is because the rate of forward reaction is equal to the rate of reverse reaction at equilibrium.
d) False
At equilibrium, both the forward and reverse reactions occur. Hence, the rate must not be zero.
e) True
This is why the system is at equilibrium.
f) False
At equilibrium, the concentration of all reactants and products are determined by the initial concentrations and the equilibrium constant. No such conclusion can be made.
g) False
This occurs only in irreversible reaction. When equilibrium is attained, the reaction must be reversible.
The answers: Circle the options c) and e)
