Portage Learning CHEM 104 Module 3 Exam.Question 1 
Show the calculation of the molar solubility (mol/L) of BaF2, Ksp of BaF2 = 1.0 x 10-6. 
Your Answer: 
Ksp = [Ba+2] [F-]2 = 1.0x10-6 
1.0x10-6 = [s] [2s]2 
1.0x10-6 = 4s3 
s = 6.3x10-3 mol/L 
Question 2 
Show the calculation of the Ksp of MnS if the solubility of MnS is 0.0001375 g/100 ml. 
MW of MnS = 87.01 
MnS (s) Mn+2 (aq) + S-2 (aq) 
Your Answer: 
molar solubility of MnS = (0.0001375 g/100 ml) x (1000 mL) x (1 mol/87.01 g MnS)

Kinetics - the study of rates of reactions and how they are 
influenced by certain factors 
Influences Reactions Rates - Concentration, temperature, 
catalysts, surface area 
Temperature/Reaction Rate - Increase, higher temperature 
provides higher kinetic energy 
Catalyst/Reaction Rate - Increase, without being consumed 
Surface Area/Reaction Rate - Increase, increased surface area 
of particles increases reaction rate because solids only react at their 
surfaces (grinding solid into fine powde...
