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

The following two reactions are known Fe_(2) O _(3 (s)) + 3 CO _((g )) to 2 Fe _((s)) +3 CO _(2 (g)) , Delta H =- 26.8 kJ//mol FeO _((s)) + CO _((g)) to Fe _((s)) +CO _(2 (g)), Delta H =- 16.5 kJ//mol The value of Delta H for the following reaction Fe _(2) O _(3 (s)) + CO _((g)) to 2 Feo_((s)) + CO _(2 (g)) is

in manufacture of NO, the reaction N_(2(g)) + O_(2(g)) hArr 2NO_((g)). Delta H + ve is favourable if :

2C_((s)) + 1/2O_(2(gg) rarr CO_(2(g)) , DeltaH = -787 KJ H_(2(g)) + 1/2O_(2(g)) rarr H_2O_((l)) , DeltaH = -286 KJ C_2H_(2(g)) + 2 1/2O_(2(g)) rarr 2CO_(2(g)) + H_2O_((l)) , DeltaH = -1301 KJ . Heat of formation of acetylene in KJ is

2H_(2(g)) + O_(2(g)) rarr 2H_(2)O_((l)) , DeltaH= -ve and DeltaG= -ve . Then the reaction is
