Q)

calculate the lattice energy of $KI,$ given that enthalphy of (i) sublimation of K is $90\;K\;J mol^{-1}$, (ii) dissociation of $I_2$ to $I^{-}$ is $213\;kJmol^{-1}$ (iii) ionisation of K to $K^{+}$ is $415\;kJ mol^{-1}$ (iv) electron affinity for I to $I^{-}$ is $-294.6 \;KJ\;mol^{-1}$ and $SH_f$ overall is $-327\;kJ\;mol^{-1}$

$(A)\;666\;KJ\;mol^{-1} \\ (B)\;644\;KJ\;mol^{-1} \\(C)\;633\;KJ\;mol^{-1} \\(D)\;650\;KJ\;mol^{-1} $
