## TlBrO3 (s) → Tl+1 (aq) + BrO3-1 (aq)

Back to reactions list

## Reaction Type:

Dissociation of an ionic compound in water

## Enthalpy of Reaction

[1ΔHf(Tl+1 (aq)) + 1ΔHf(BrO3-1 (aq))] - [1ΔHf(TlBrO3 (s))]
[1(5.4) + 1(-83.68)] - [1(-136.4)] = 58.12 kJ
58.12 kJ     (endothermic)

## Entropy Change

[1ΔSf(Tl+1 (aq)) + 1ΔSf(BrO3-1 (aq))] - [1ΔSf(TlBrO3 (s))]
[1(125.5) + 1(163.18)] - [1(168.62)] = 120.06 J/K
120.06 J/K     (increase in entropy)

## Free Energy of Reaction (at 298.15 K)

From ΔGf° values:
[1ΔGf(Tl+1 (aq)) + 1ΔGf(BrO3-1 (aq))] - [1ΔGf(TlBrO3 (s))]
[1(-32.4) + 1(1.67)] - [1(-53.14)] = 22.41 kJ
22.41 kJ     (nonspontaneous)

From ΔG = ΔH - TΔS:
22.32 kJ     (nonspontaneous)
