CHM142 Final Exam Review with correct
solutions 2024/2025 University of Miami |
100% RATED CORRECT!!
solution
- evenly spread or "homogenous" mixture of two or more substances
- Can have a combo of 3 phases of matter
solvent
Substance present in the largest amount
solute
Any substance in a smaller amount
solubility
Degree to which a substance can dissolve in a given solvent
unsaturated
- Contains less solute than it has the capacity to dissolve
- Stable when disturbed
saturated
- Contains maximum amount of a solute that can dissolve
supersaturated
- Contains more dissolved solute
- Small disturbance causes solute to crystalize
instantaneous dipole
- Inducing a nearby nonpolar molecule
- Larger molecules generate larger dipole when they are induced
- Solutes more soluble in a solvent if they have greater IMFS
like dissolves like
- Substances with similar types and magnitudes of intermolecular forces in their pure forms will
be the most soluble in solution
, what will form a solution
- Two polar molecules
- A nonpolar molecule and a polar molecule
what will not form a solution
- A polar and nonpolar molecule
colligative properties
- Depends on the number of solute particles
- Do not depend on the nature of the solute particles
vapor pressure
- Pressure exerted by the molecules that have escaped to the gas phase, once pressure has
stopped increasing
- Reduced by presence of a solute
semipermeable membrane
- Allows the passage of solvent molecules but blocks the passage of solute molecules
chemical kinetics
- Study of how fast reactions take place
what causes a chemical reaction slow down
as reactants are consumed
secant line
- Line which intersects two points on the curve
- Correspond to the "average rate"
tangent line
- Intersects curve at a single point perpendicular to normal line
- Correspond to "instantaneous rate"
rate law
- An equation relating the rate of reaction to the concentration of reactants
- Only contains concentrations of reactants
integrated rate law
- Describes the concentration of a reactant at any time
