Answer 1

Let us suppose the equation reaction :-
$a A + b B ⇌ c C + d D$

$K_{e q} = \frac{[ C ] ^{c} [ D ] ^{d}}{[ A ] ^{a} [ B ] ^{b}}$

Unit of $K_{e q} = \frac{( m o l / L ) ^{d} . ( m o l / L ) ^{c}}{( m o l / L ) ^{a} ( m o l / L ) ^{b}}$
$= (m o l / L)^{(c + d) - (a + b)}$

$= (m o l / L)^{△ n}$

$△ n =$ no. of moles of (products - reactants)

Answer 2

Let us suppose the equation reaction :-

a A + b B ⇌ c C + d D

K_{e q} = \frac{[ C ] ^{c} [ D ] ^{d}}{[ A ] ^{a} [ B ] ^{b}}

Unit of

K_{e q} = \frac{( m o l / L ) ^{d} . ( m o l / L ) ^{c}}{( m o l / L ) ^{a} ( m o l / L ) ^{b}}

= (m o l / L)^{(c + d) - (a + b)}

= (m o l / L)^{△ n}

△ n =

no. of moles of (products - reactants)
