Hello everyone, I am a Canadian student preparing for the upcoming CCO. When I was doing Problem Set#3 on the official website, I couldn't get the correct answer from these two following problems. Could someone help me out?
#1 By how much does the solubility of silver chloride increase when you increase the temperature of the solution from 10 to 90 degree celsius.
a. 170x b. 21x c. 76x d. 214x e. 14x...
The data give are AgCl (standard heat of formation (kJ/mol): -127 standard entropy (J/mol): -109)
Ag+ (105, 77)
Cl- (-167, -131)
#2 A plume of air near a smoke stack contains a partial pressure of sulfur dioxide gas of 1.0*10^-7 atm, using the equilibrium reaction shown below calculate the pH of cloud droplets that form in this air plume?
SO2(g) + 2H2O(l) = HSO3-(aq) + H3O+(aq) K=1.7*10^-2
a. 2.79 b. 5.56 c. 3.26 d. 2.55 e. 4.38
Thank you very much if you could show me the full solution!
