$K_1 = 4.2 \times 10^{-7}$ and $K_2 = 4.8 \times 10^{-11}$
Select the correct statement for a saturated $0.034\, M$ solution of the carbonic acid.
$A.$ Surface tension is the outcome of equal attractive and repulsion forces acting on the liquid molecule in bulk.
$B.$ Surface tension is due to uneven forces acting on the molecules present on the surface.
$C.$ The molecule in the bulk can never come to the liquid surface.
$D.$ The molecules on the surface are responsible for vapour pressure if the system is a closed system.
$A ( g ) \rightleftharpoons B ( g )+\frac{1}{2} C ( g )$
the relation between dissociation constant ( $K$ ), degree of dissociation $(\alpha)$ and equilibrium pressure $(p)$ is given by?
