Which of the following salts on dissolution in water gives $pH$ less than $7$ at $298 \ K$?

If $0.1 \, M \, CH_3COONa$ undergoes $1 \%$ hydrolysis,then the values of $K_h$,$K_a$ of the acid,and the concentration of $CH_3COOH$ are respectively:

If the value of $K_b$ is $10^{-5}$,find the $K_h$ value for a salt of (strong acid - weak base) at $363 \ K \ (90 \ ^\circ C)$. [At $90 \ ^\circ C, K_w = 10^{-12}$]
