Options

A. Higher hydration enthalpy of `Li^(+)`, higher lattice enthalpy of `Cs^(+)`
B. Smaller hydration enthalpy of `Li^(+)` higher lattice enthalpy of `Cs^(+)`
C. Smaller lattice enthalpy of `Li^(+)`, higher hydration enthalpy of `Cs^(+)`
D. Higher lattice enthalpy of `Li^(+)`, smaller hydration enthalpy of `Cs^(+) ` .

Answer

D
