33. The solubility of solid silver chromate, Ag2CrO4 (Ksp =9.0 × 10-12) in 0.500 M solution of K2CrO4 at 25oC is (A) 1.8×10-11 (B) 4.2×10-6 (C) 2.1×10-6 (D) 1.3×10-4

36. For the reaction A + B $\rightleftharpoons$ C + D, $\Delta H^\circ = +40$ kJ and $\Delta S^\circ = +50$ J/K. Therefore, the reaction under standard conditions is (A) spontaneous at temperatures less than 10 K (B) spontaneous at temperatures greater than 800 K (C) spontaneous only at temperatures between 10 K and 800 K (D) spontaneous at all temperatures
