A- is a weak base. which equilibrium corresponds to the equilibrium constant ka for ha?

vekshin1

Answer:

$K_a=\frac{[H^+][A^-]}{[HA]}$

Explanation:

ka is defined as the dissociation constant of an acid. It is defined as the ratio of concentration of products to the concentration of reactants.

For the dissociation of weak acid, the chemical equation follows:

$HA\rightleftharpoons H^++A^-$

The equilibrium constant is defined by the equilibrium concentration of products over reactants:

$K_a=\frac{[H^+][A^-]}{[HA]}$

I think the correct answer would be the third option. The reason I2 has a higher melting point than F2 is because I2 possesses a more polarizable electron cloud. I2 contains more electrons than F2 which would result to a stronger intermolecular forces. Having stronger intermoleculer forces would mean more energy is needed to break the bonds so a higher melting point would be observed.
