Calculate the lattice energy of the reaction
`Li^(o+)(g) +CI^(Theta) (g) rarr LiCI(s)`
from the following data:
`Delta_("sub")H^(Theta)(Li) = 160.67 kJ mol^(-1), (1)/(2)D(CI_(2)) = 122.17 kJ mol^(-1) , IP(Li) = 520.07 kJ mol^(-1)`, `E_(A)(CI) = - 365.26 kJ mol^(-1)` and `Delta_(f)H^(Theta)(LiCI) =- 401.66 kJ mol^(-1)`

Text Solution

Verified by Experts

Applying the equation
`-Q=DeltaH+(1)/(2)D+IP-EA+U`
and substituting the respective values,
`-401.66=160.67+122.17+520.07-365.26+U`
`U=-839.31kJ" "mol^(-1)`
