Class 11th

CH₃COONa is salt of weak acid with strong base

$\therefore pH=7+\frac{1}{2}p{K}_a+\frac{1}{2}logC$

$pH=7+\frac{1}{2}*4.74+\frac{1}{2}*log1$

$pH=9.37\approx 9.4$

On increasing pressure, equilibrium moves in that direction where number of gaseous moles decreases.

  $\Delta G=\Delta H-T\Delta S$

For spontaneity

$\begin{array}{l}\Delta G=-ve\\ \Delta S=+ve\\ \Delta H=-ve\end{array}$        

Kindly go through the solution

K_h = Kw/Ka = 2.22 x 10^-5

Total kinetic energy associated with 'n' moles of monoatomic gas is =   $\frac{3}{2}nRT$

NH₃ can be liquefied most easily due to presence of strong intermolecular H-bonding among NH₃ molecules.

2-chloro-4-methylanisole

Electron withdrawing group decreases the stability of carbocation.

Correct order of stability of carbocation is
