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) molar solub...

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...
