Abstract
The enthalpies of formation of crystalline uranyl pyrovanadate and uranovan adic acid at 298.15 K were determined. The temperature dependences of the h eat capacities of uranyl pyrovanadate and uranovanadic acid were studied in the temperature ranges 5-300 and 7-300 K, respectively. The enthalpies, th e entropies, the Gibbs functions, and the equilibrium constants of two reac tions with the formation of uranovanadic acid at 298.15 K were calculated.
