Question

The equilibrium between gaseous isomers A, B and C can be represented as:
$A\left(g\right)\leftrightharpoons B\left(g\right);K_1=?$
$B\left(g\right)\leftrightharpoons C\left(g\right);K_2=0.4$
$C\left(g\right)\leftrightharpoons A\left(g\right);K_3=0.6$
If one mole of A is taken in closed vessel of volume 1 L, then

• A. [A] + [B] + [C] = 1 M at amy moment of reaction.
• B. Concentration of C is 1.2 M at equilibrium
• C. The value of $K_1$ is 1/0.24
• D. Isomer A is thermodynamically least stable

Answer 1

Answer: (A), (C), (D)

The correct options are
A [A] + [B] + [C] = 1 M at amy moment of reaction.
C The value of $K_1$ is 1/0.24
D Isomer A is thermodynamically least stable
