This question has Statement I and Statement It. Of the four choices given after the Statements, choose the one that best describes the two Statements
Statement - I: The equilibrium mixture
`Co(H_2O)"_6^(2+) (aq) + 4 Cl^- (aq) iff CoCl"_4^(2+) (aq) + 6H_2O(l)`
turns pink from deep blue on cooling in a freezing mixture.
Statement.II : The reaction is endothermic. On cooling, equilibrium shifts in the backward direction.
