General Chemistry 2 Notes:   Molality: Moles of solute/ kg of solvent   Parts by mass: mass of solute/ mass of solution   Parts by volume: volume of solute/ volume of solution  Mole fraction: moles of solute/ mol of solute + mol of solvent   Parts per million: (mass of solute/ total mass of solution) x 10 ^6  ­ These are all important equations that will need to be known for the exam.   Colligative Properties: Adding solutes to a solvent alters physical properties of that  solvent.  ­ Vapor pressure reduction  ­ Boiling point elevation ­ Freezing point depression ­ Osmotic pressure changes  ­ These properties only depend on the # of solute particles that have dissolved.  ­ Therefore, it is important to remember solubility of compounds and salts.   Solute’s presences lowers the mole fraction of the solvent and therefore the vapor  pressure is reduced and less particles can leave the solution.   Nonvolatile non­electrolytic solutions:  ­ Vapor pressure lowers due to the fact that solute addition increases entropy.  ­ Vapor pressure exists in support of entropy and when the entropy is increased due to a  solute’s presence the vapor pressure may decrease.  ­ Think of it this way: If you have to eat 3 hamburgers to be full, but you eat a lot of fries  before you eat the burgers, you have to eat less burgers to be full!  So, if the vapor  pressure has to be a certain level to meet the required entropy, but the solute adds  entropy, then the vapor pressure may decrease.  ­ Change in vapor pressure is shown by Raoult’s Law:  ­  X is the mole fraction of the solution  ­ P^o a is the vapor pressure of the pure solvent.   Boiling point elevation occurs as well: Solution boils at a higher temperature.  ­ This process is shown by this equation… ­ Kb is a constant that is given  ­ m is the molality of the solution   Freezing point depression also occurs: A solution freezes at a lower temperature.  ­ This process is shown by the exact same equation above.   Osmotic Pressure: This is the pressure required to block osmosis (π)  ­ The equation is π= mrt  ­ M is the molarity  ­ R is the constant .08206L per atm/mol x K  ­ T is the temperature in kelvins   Colligative properties of volatile nonelectrolytic solutions:  ­ Volatility and vapor pressure of both are depressed.   Strong electrolytic solutions:  ­ These involve dissociation of ions, so we must multiply every equation by the van’t Hoff  factor.  ­ The van’t Hoff factor is merely: I = measured value for electrolytic solution/ expected  value.   Molarity x seconds is the speed of reactions.   Chemical Kinetics: Study of reaction rates.   4 factors determine speed of a reaction:                  ­ Concentration      ­ Physical states of the solution                 ­ Temperature: Higher temps increase reaction rates.      ­ Presence of a catalyst: Lower activation energy.   Reaction rate: Change in concentration / change in time.   For reactions involving coefficients, use the equation: aA + bB yields cC + dD.   The equations for this part are best acquired in class, for I haven’t the ability to type them properly…..  Rate law expression: For instantaneous rates,  ­  Rate = k[A]^x[B]^y  ­ k is the rate constant ­x and y are the orders of reaction with respect to the reactants  ­ Rate law only includes reactions!!! ­ Reaction orders are determined by experiment.   First order reactions are when the rate of A is directly proportional to the  concentration. So, if A doubles, then the concentration doubles as well.   Second order reactions are when the rate is the square of the concentration. So, if A  doubles, then the concentration quadruples. Or, if A triples, then the concentration is  multiplied by 9.   Zero order reactions are when the Rate has no effect on the concentration……   These reaction orders cannot be determined from balanced chemical equations.

Why people love StudySoup

Steve Martinelli UC Los Angeles

"There's no way I would have passed my Organic Chemistry class this semester without the notes and study guides I got from StudySoup."

Jennifer McGill UCSF Med School

"Selling my MCAT study guides and notes has been a great source of side revenue while I'm in school. Some months I'm making over $500! Plus, it makes me happy knowing that I'm helping future med students with their MCAT."

Bentley McCaw University of Florida

"I was shooting for a perfect 4.0 GPA this semester. Having StudySoup as a study aid was critical to helping me achieve my goal...and I nailed it!"


"Their 'Elite Notetakers' are making over $1,200/month in sales by creating high quality content that helps their classmates in a time of need."
