Final review Flashcards
(36 cards)
Zero order in respect to rate law
Rate = K, rate does not depend on conc
First order in respect to rate law
Rate = K[A]^1, rate depends on conc.
Second order in respect to rate law
Rate = K[A]^2, doubling or tripling conc affects the rate, 2^2 = 2, or 3^3 = 9
Atomic radius periodic trend
- increase as amu increases
- bottom left side; biggest
Ionic radius energy periodic trend
- more positive; smaller radius (Mg2+<Mg+)
- more negative greater radius
Ionization energy
- energy required to remove an electron
- top right side; highest ionization energy
Electron affinity
- top right side; highest EA
Highest metallic character
bottom left side
bottom left side of the periodic table trend
Highest metallic character and atomic radius
Top right side of the period table trend
Highest ionization energy and electron affinity
polar or non polar if dipoles cancel out
polar molecule
polar or non polar if dipoles dont cancel out
non polar
Which t1/2 order depends on conc
Zero and Second order
Which t1/2 order does not depend on conc
First order
t1/2 always depends on
K (rate constant)
As concentration increases what happens to t1/2 in respect to zero order
t 1/2 increases
As concentration increases what happens to t1/2 in respect to second order
t 1/2 decreases
As concentration increases what happens to t1/2 in respect to first order
no effect on t 1/2
what form of radiation has the lowest energy per photon
radio waves
mass of an electron
9.11x10^-31
Electronegtivity 0.5 - 1.9
polar
Electronegativity 1.9 - 2.0
more ionic character compared to 0.5 - 1.9
intermolecular force
- all molecules (polar & non polar)
- temporary dipoles
- increases with molar mass & polarizability
How to determine and compare the stability of ions (E.g. F2, O2^2+)
B.O = Electrons in antibonding - electrons in bonding
