In which of the following process of neutralization is the magnitude of `Delta H_("neutralization")` less than that of `Delta H_("ionization") of water ?

Options

A. `2CO(g) + O_(2) (g) rarr 2CO_(2)(g)`
B. `N_(2)(g) + O_(3) (g) rarr N_(2)O_(3) (g)`
C. `CH_(4) (g) + 2Cl_(2)(g) rarr CH_(2)Cl_(2) (l) + 2HCl(g)`
D. `Xe(g) + 2F_(2) (g) rarr XeF_(4)(g)`

Answer

D

Explanation

Both Xe and `F_(2)` are gaseous elements at `25^(@)C` and in their standard states and form `XeF_(4(g))`. Hence, `Delta H_((f))^(@) = Delta H_("react")^(@)`
