Using the data given below,predict the nature of heat changes for the reaction .
`Mg_(g) + 2F_(g) rarr Mg_(g)^(2+) +2F_(g)^-`
`IE_1` and `IE_2` of `Mg_(g) `are `737.7 ` and `451 kJ "mol"^(-1)` . `EA_1 ` for `F_(g)` is `-328 kJ "mol"^(-1)`.
A. `1232.4 KJ "mole"^(-1)`
B. `+1532.7 KJ "mole"^(-1)`
C. `-1232.4 KJ "mole"^(-1)`
D. `-1532.7 KJ "mole"^(-1)`
