Which of the following statements is incorrect regarding reaction quotient (Q) ?

Options

A. `Q=K_f/K_b xx R_b/R_f`
B. Value of Q increases as reaction proceeds in forward direction.
C. Q = K = 1 at equilibrium
D. Value of Q can be greater than value of K.

Answer

C

Explanation

`R hArr P`
`R_f =K_f [R]`….(1)
`R_b = K_b [P]`….(2)
Equation (2) `divide` Equation (1)
`R_b/R_f=K_b/K_fxx "[P]"/"[R]"`
or `R_b/R_f=K_b/K_f Q`
or `Q=R_b/R_f xx K_f /K_b`
