MCQ
Consider the imaginary equilibrium $4A + 5B$ $\rightleftharpoons$ $ 4X + 6Y$ The equilibrium constant ${K_c}$ has the unit
  • A
    Mole$^{2}$ litre$^{-2}$
  • B
    Litre mole$^{-1}$
  • ✓
    Mole litre$^{-1}$
  • D
    Litre$^{2}$ mole$^{-2}$
✓

Answer

Correct option: C.
Mole litre$^{-1}$
(c) Unit of ${K_c} = $(unit of concentration)$^{\Delta n}$

= (mole/litre)$^{\Delta n}$

$\Delta n = 10 -9 = 1$

$\therefore $ ${K_c} = $ mol/Litre
