The value of `DeltaH^(@)` for the reaction `Cu^(+)(g)+I^(-)(g)toCuI(g)` is -446kJ `mol^(-1)`. If the ionisation energy of `Cu(g)` is 745 kJ `mol^(-1)` and the electron affinity of I(g) is -295 kJ `mol^(-1)`, then the value of `DeltaH^(@)` for the formation of one mole of CuI(g) from Cu(g) and I(g) is:
A. `-446kJ`
B. 450 kJ
C. 594 kJ
D. 4 kJ
