The concentration of 2NO_(2)(g)hArrN_(2)O_(4)(g) is an exothermic equilibrioum . This means that:

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)

The enthalpy of formation of N_2O_((g)) and NO_((g)) are 82.0 KJ and 90 KJmol^(-1) respectively. The enthalpy of the reaction 2N_2O_((g)) + O_(2(g)) rarr 4NO_((g)) is

Which of the indicated relationship is correct for the following exothermic reaction carried out at constant pressure? CO_((g)) + 3H_(2(g)) rarr CH_(4(g)) + H_(2)O_((g))

The enthalpy of the reaction H_(2(g)) + O_(2(g)) rarr H_2O_((g)) is DeltaH_1 and that of H_(2(g)) + O_(2(g)) rarr H_(2)O_((l)) is Delta H_2 . Then

Assertion (A): The enthalpy of formation of H_(2)O_((l)) is greater than that of H_(2)O_((g)) Reason (R ): Enthalpy change is negative for the condensation reaction H_(2)O_((g)) rarr H_(2)O_((l))

Standard Enthalpy (Heat) of formation of liquid water at 25^@C is around H_2(g) + 1/2 O_2(g) rightarrow H_2O_(l).

At T(K), the ratio of kinetic energies of 4g of H_(2) (g) and 8g of O_(2) (g) is
