Differentiate irreversible and reversible reactions.

 

For the equilibrium. ${\mathrm{BaSO}}_4\left(\mathrm{g}\right)\rightleftharpoons {\mathrm{Ba}}^{2\oplus }\left(\mathrm{aq}\right)+{\mathrm{SO}}_4{}^{2\ominus }(\mathrm{aq})$, state the effect of addition of ${\mathrm{Ba}}^{2\oplus }$ ion.

For the equilibrium. ${\mathrm{BaSO}}_4\left(\mathrm{g}\right)\rightleftharpoons {\mathrm{Ba}}^{2+}\left(\mathrm{aq}\right)+{\mathrm{SO}}_4^{2-}\left(\mathrm{aq}\right)$, state the effect of removal of ${\mathrm{SO}}_4^{2-}$ion.

For the equilibrium. ${\mathrm{BaSO}}_4\left(\mathrm{g}\right)\rightleftharpoons {\mathrm{Ba}}^{2\oplus }\left(\mathrm{aq}\right)+{{\mathrm{SO}}_4}^{2⊝}\left(\mathrm{aq}\right)$, state the effect of addition of ${\mathrm{BaSO}}_4\left(\mathrm{s}\right)$ on the equilibrium.

State and explain Le Chatelier's principle suitably with reference to change in temperature.
