NEET · Chemistry · STD 11 - 6.1. Equilibrium - 1 (chemical Equilibrium)

For the reaction \(2 \mathrm{~A} \rightleftharpoons \mathrm{B}+\mathrm{C}, \mathrm{Kc}=4 \times 10^{-3}\). At a given time, the composition of reaction mixture is: \([A]=[B]=[C]=2 \times 10^{-3} \mathrm{M}\). Then, which of the following is correct?

  1. A  Reaction has a tendency to go in forward direction.
  2. B  Reaction has a tendency to go in backward direction.
  3. C  Reaction has gone to completion in forward direction.
  4. D  Reaction is at equilibrium.
Verified Solution

Answer & Solution

Correct Answer

(B)  Reaction has a tendency to go in backward direction.

Step-by-step Solution

Detailed explanation

\(2 \mathrm{~A} \rightleftharpoons \mathrm{B}+\mathrm{C}, \mathrm{K}_{\mathrm{c}}=4 \times 10^{-3}\) At a given time \(\mathrm{t}, \mathrm{Q}_{\mathrm{c}}\) is to be calculated and been compared with \(\mathrm{K}_{\mathrm{c}}\).
