Question

The unit of equilibrium constant for the following reaction is 2NO2 (g) leftharpoons N2O4(g) (A) mol L-1 (B) L mol-1 (C) mol-1 L-1 (D) equilibrium constant is unitless

Tardigrade Admin · Accepted Answer

2 NO 2(g) leftharpoons N 2 O 4(g) Kc =([ N 2 O 4]/[ NO 2]2)=( Mol L -1/( Mol L -1)2)= L Mol -1

Q. The unit of equilibrium constant for the following reaction is
$2 N O_{2} (g) ⇌ N_{2} O_{4} (g)$

$m o l L^{- 1}$

$L m o l^{- 1}$

$m o l^{- 1} L^{- 1}$

equilibrium constant is unitless

$2 N O_{2} (g) ⇌ N_{2} O_{4} (g)$

$K_{c} = \frac{[ N _{2} O _{4} ]}{[ N O _{2} ] ^{2}} = \frac{M o l L ^{- 1}}{( M o l L ^{- 1} ) ^{2}} = L M o l^{- 1}$
