easy

For the reaction in aqueous solution $Z{n^{2 + }} + {X^ - } \rightleftharpoons Zn{X^ + },$ the ${K_{eq}}$ is greatest when $X$ is

A

${F^ - }$

B

$NO_3^ - $

C

$ClO_4^ - $

D

${I^ - }$

Solution

(a) Because of ${F^ – }$is a highly electronegative. So it is easily lose the electron and reaction occur rapidly.
