In aqueous solutions `H_(2) SO _(4)` ionises as:
`H _(2) SO_(4) + H _(2) O hArr H _(2) SO _(24 ) ^(-) + H _(3) O ^(+) , K a _(1)`
`H_(2) SO _(4) ^(-) + H_(2) O hArr SO _(4) ^(2-) + H_(3) O ^(+) , Ka _(2).`
The relation between `Ka _(1) and Ka _(2) ` is

A

`Ka _(1) lt Ka _(2)`

B

`Ka _(1) gt Ka _(2)`

C

`K a _(1) = Ka _(2)`

D

`2 Ka A_(1) = 3 Ka _(2)`
