Ni(II) compounds are thermodynamically more stable than Pt(II)- Justify your answer. |
|
Answer» Solution :(i) The IONISATION enthalpy values can be used to predict the THERMODYNAMIC STABILITY of their compounds. (ii) `{:("For Nickel,"I.E_(1)+I.E_(2),=,737+1753),(,=,2490" kJ mol"^(-1)),("For Platinum,"I.E_(1)+I.E_(2),=,864+1791),(,=,"2655 kJ mol"^(-1)):}` Since, the energy required to FORM `NI^(2+)` is less than that of `Pt^(2+), Ni(II)` compounds are thermodynamically more stable than `Pt(II)` compounds. |
