Comment on the thermodynamics stability of `NO_((g))` given that
`1/2N_(2(g))+1/2O_(2(g)) to NO_(g),Delta_(r)H^(theta)=90kJmol^(-1)`
`NO_((g))+1/2O_(2(g))to NO_(2(g)),Delta_(r)H^(theta)d=-74 Kjmol^(-1)`

Text Solution

Verified by Experts

Exothermic compounds are stable while endothermic compounds are unstable. No is endothermic compound so unstable. `NO_(2)` is exothermic compound so stable.

The enthalpy of the reaction H _(2 (g)) + 1/2 O _(2(g)) to H _(2) O _((g)) is Delta H _(1) and that of H _(2(g)) + 1/2 O _(2(g)) to H _(2) O _((l)) is Delta H _(2). Then

The formation of the oxide ion O _((g)) ^(2-) from oxygen atom requires first an exothermic and then an endothermic step as shown below : O _((g)) + e ^(-) to O _((g )) ^(-) ,Delta _(f) H^(0) =-141 kJ mol ^(-1) O _((g)) ^(-) +e ^(-) to O _((g)) ^(-2) ,Delta _(f) H^(0) =+ 780 kJ mol ^(-1) Thus, process of formation of O^(2-) in gas phase is unfavourable even thrugh O ^(2-) is isoelectronic with neon. It is due to the fact that (2015)
