At temperature T1 = 2000 K and normal pressure, the degree of hydrogen dissociation a1 = 8.4 • 10-4, i.e. the fraction of H2 molecules disintegrated into atoms is equal to a1. At temperature Tg = 2500 K and the same pressure, the degree of dissociation is a2 = 1.33 • 10-2. Determine the heat of reaction of hydrogen dissociation.
