314828 When hydrochloric acid is added to cobalt nitrate solution at room temperature, the following reaction takes place and the reaction mixture becomes blue. On cooling the mixture it becomes pink. On the basis of this information mark the correct answer.
\(\left[ {{\text{Co(}}\mathop {{{\text{H}}_{\text{2}}}{\text{O}}}\limits_{{\text{Pink}}} {{\text{)}}_{\text{6}}}} \right]_{{\text{(aq)}}}^{{\text{3 + }}}{\text{ + 4Cl}}_{{\text{(aq)}}}^{{\text{ - }}} \rightleftharpoons \left[ {\mathop {{\text{CoC}}{{\text{l}}_{\text{4}}}}\limits_{{\text{(blue)}}} } \right]_{{\text{(aq)}}}^{{\text{2 - }}}{\text{ + 6}}{{\text{H}}_{\text{2}}}{\text{O}}\)

314829 Assertion :
According to Le Chatelier's principle addition of heat to an equilibrium
[Solid \(\rightleftharpoons\) liquid] results in decrease in the amount of solid.
Reason :
Reaction is endothermic, so on heating forward reaction is favoured.

314830 Assertion :
On cooling in a freezing mixture, colour of the following mixture turns to pink from deep blue for the reaction \({\text{Co}}\left( {{{\text{H}}_{\text{2}}}{\text{O}}} \right)_{{\text{6(aq)}}}^{{\text{2 + }}}{\text{ + 4Cl}}_{{\text{(aq)}}}^{\text{ - }} \rightleftharpoons {\text{CoCl}}_{{\text{4(aq)}}}^{{\text{2 - }}}{\text{ + 6}}{{\text{H}}_{\text{2}}}{{\text{O}}_{{\text{(1)}}}}\)
Reason :
Reaction is endothermic. So on cooling, the reaction moves to backward direction.

314831 In the dissociation of \(2 \mathrm{HI} \rightleftharpoons \mathrm{H}_{2}+\mathrm{I}_{2}\), the degree of dissociation will be affected by the

314833 \({{\text{N}}_{{\text{2}}\left( {\text{g}} \right)}}{\text{ + 3}}{{\text{H}}_{{\text{2}}\left( {\text{g}} \right)}} \rightleftharpoons {\text{2N}}{{\text{H}}_{{\text{3}}\left( {\text{g}} \right)}}{\text{ + }}\) heat
What is the effect of the increase of temperature on the equilibrium of the reaction?
