Which of the following reactions require largest amount of energy?

1.	Which of the following reactions require largest amount of energy?
Answer» `Ga_((G))^(2+) to GA _((g))^(3+) + e^(-)` `Ga_((g)) to Ga_((g))^(+) + e^(-)` `Ga_((g))^(+) to Ga_((g))^(2+) + e^(-)` All the reactions require same amount of energy. Solution :(A)`Ga_((g))^(2+) to Ga _((g))^(3+) + e^(-)` (B) `Ga_((g)) + to Ga_((g))^(+) + e^(-) Delta_(i)H_(1)` (First ionization Energy) (C ) `Ga_((g))^(+) to Ga_((g))^(2+) + e^(-) Delta_(i)H_(2)` (Second ionization Energy) (A) `Ga_((g))^(2+) to Ga_((g))^(3+) + e^(-) Delta_(i)H_(3)` (Third ionization Energy) The value of next ionization ENTHALPY INCREASES graduaely as `Delta H_(1) lt Delta_(i)H_(2) lt Delta_(i)H_(3) `.... According to this reaction requires largest amount of energy.
