Transcribed Image Text:Q.30. Determine, at 298 K, A,H°, the standard enthalpy of the
reaction (1) between dinitrogen tetraoxide and hydrazine:
(1)
N,0, (g) + 2 N,H, (1) à 3 N, (g) + 4 H,O (g)
Knowing the standard reaction enthalpies, at 298 K, of the
following reactions:
(2) NH, (g)à 1/2 N, (g) + 3/2 H, (g); A„H° = + 46,19 kJ . mol-
(3) N,O4 (g) à 2 NO, (g) ; A3H°:
(4) 2 NH; (g) à N,H (1) + H, (g) ; A„H° = + 142,80 kJ . mol-'
(5) 2 NO, (g) + 4 H, (g) à N, (g) + 4 H,O (g) ; AşH° = – 1
