Question

If a liquid Fe V solution is equilibrated with pure solid VO and a gas containing Po2=4.72x10-10 atm, at 1800°C calculate the activity of V in the liquid solution with respect to the Henrian standard state. For the change of standard state V(s) V(1wt% in Fe) AGº--15480-45.61T in Joules. The standard Gibbs free energy change for the reaction Vel) + 1/2O2(g) VO(s) is AGº--424700+80.041 in the temperature range of 298K and 2000K. Molar mass of Fe is 55.85 g/mol and molar mass of V is 50.94 g/mol. Lütfen birini seçin: a. 4.1x10-2 b. 1.9x102 c. 7.8x102 d. 6 2x10-2 e9.0x102
