Embibe Experts Solutions for Exercise 2: Assignment

Which of the following reactions has minimum value of $\frac{{\mathrm{K}}_{\mathrm{P}}}{{\mathrm{K}}_{\mathrm{C}}}?$

Consider the following graph for the chemical reaction
${\mathrm{H}}_2( \mathrm{g})+{\mathrm{I}}_2\left(\mathrm{g}\right)\rightleftharpoons 2\mathrm{HI}\left(\mathrm{g}\right)$

The inference that can be obtained from this graph about chemical equilibrium is that

Out of the following, choose an incorrect statement.

The ${\mathrm{pK}}_{\mathrm{a}}$ and ${\mathrm{pK}}_{\mathrm{b}}$ value of acetic acid and ammonium hydroxide are $4.78$ and $4.7$ respectively, then the $\mathrm{pH}$ of ammonium acetate solution is

The dissociation constant of a weak monoacidic base is ${10}^{-5} .$ The $\mathrm{pH}$ of its $0.1\mathrm{M}$ solution will be approximately equal to

$\mathrm{HF}+{\mathrm{H}}_2\mathrm{O}\stackrel{{\mathrm{k}}_1}{⟶}{\mathrm{H}}_3{\mathrm{O}}^{+}+{\mathrm{F}}^{-}$
${\mathrm{F}}^{-}+{\mathrm{H}}_2\mathrm{O}\stackrel{{\mathrm{K}}_2}{⟶}\mathrm{HF}+{\mathrm{OH}}^{-}$
