Question

Which of the following is true for the sublimation of a solid substance? Under standard-state conditions, which of the following species is the best reducing agent Rank the following salts in order of increasing molar solubility A certain reaction is found to favor products. Which of the following is a correct description of the reaction? Find Delta G degree at 298 K for the following reaction Consider the following standard reduction potentials: Which pair of substances will react spontaneously under standard-state conditions?

Explanation / Answer

8) Sublimation of solid substance is a spontaneous process at room temperature and pressure This process requires energy (H > 0), and a solid-to-gas conversion always shows as S > O

9) Ag+ is best reducing agent because reducing potential is heigh

10)  CdS < BaSO4 < AgCl < CaCO3 < PbSO4 increasing ksp value of respectively salt have increasing molar solubility

11) for favour product k >1 is spontanious reaction so delta G<0

12)delta G = deltaH -TdeltaS

deltra G = -3.59 x 10^3kj

13) answer is B cd with sn
