Abstract

The reaction of superconducting YBa₂Cu₃O_y powder with water is studied kinetically. The initial rate law is found as where [S]_o is the initial surface area of the solid, a and b is found to be 0.94 ± 0.02 and 0.318 ± 0.002, respectively. For 100.7 mg powder with a mean radius of 0.0265 mm at pH 7.00 and 298 K, R_o is 2.21 × 10^-4mol · min^-1. Using a = 1 and b = 0.3, the rate constant, k, obtained at 283, 298 and 313 K is 0.64, 1.84 and 4.91 × 10^-3mol · min^-1 · cm^-2 · M^-0.3, respectively. The activation energy is 50.0 kJ · mol^-1 and pre-exponential factor is 1.09 × 10⁶mol · min^-1 · cm^-2· M^-0.3, as calculated from the Arrhenius equation.
