When is a reaction at equilibrium?
a. When K=1
b. When all concentrations are equal
c. When Q=1
d. When all concentrations are equal to 1 M or 1 atm
e. None of the above
Solution
ans- e) None of the above.
a) The value of K doesnot define a reaction at equilibrium. Although K can only be defined at
equilibrium
b) At equilibrium, rate of forward reaction = rate of backward reaction. It has nothing to do with
equal concentration. The concentration of reactants and products may or may not be equal at
equilibrium
c) Reaction quotient is not defined at equilibrium
d) Concentration doesnot define a reaction at equilibrium
