Question

Consider the following processes and respective energy change-
$M (s) \to M (g) . . . . . (a)$
$M (s) \to M^{2 +} (g) + 2 e^{-} . . . . . (b)$
$M (g) \to M^{+} (g) + e^{-} . . . . . (c)$
$M^{+} (g) \to M^{2 +} (g) + e^{-} . . . . . (d)$
$M (g) \to M^{2 +} (g) + 2 e^{-} . . . . . (e)$
Energy required to change $M (s)$ into $M^{+} (g)$ is -
