Not all chemical reactions proceed to a stage at which the concentrations of the reactants become vanishingly small. Here we consider the kinetics of such reactions.
Let a reaction be represented in general terms by the scheme
where k., and k_., represent the rate constants for the forwards and reverse reactions, respectively. The equilibrium constant for this reaction may be written as
K = [B] /[A] = K1/K–1                   --(1)
where the subscript 00 refers to a time t, sufficiently long to establish equilibrium at the given temperature. The initial concentration of species A is [A]O, and that of B is [B]O . After a time t, let the concentration of species A be [A/t and that of B be [Bat. The total rate of change of [At is given by
d[A]t/dt= - K1[A]t + k-1[B]t
If, as is usual, [B]O is initially zero, it follows from a mass balance that at any time t,
[Bat = [A]0 - [A]t, whence
d[A]t/dt = –K1[A]t + k-1([A]O - [A]t)
or
d[A]t/dt = – (K1 + k-1
What is the Cc of the reaction ​?
  • a)
     2/3
  • b)
    3/2
  • c)
    1
  • d)
    None of these
Correct answer is option 'D'. Can you explain this answer?
