>graphs for when charge accumulates on the plates of a capacitor after

switch is closed

>09.17

*greater vapor pressure, greater rate of evaporation

>09.29

rate law graphs:

for zero order, [A] vs. time is linear

*conversely, ln[A] vs. time, and 1/[A] are non-linear

for first order, ln[A] vs. time is linear


2/15

for second order, 1/[A] vs. time is linear

*excess concentrations of one reactant in second order reactions while

holding the others constant usually make it a pseudo-first order reaction

hence why in the passage:

fundamental mode of oscillation -> fundamental frequency n lambda

L = n*lambda/2 .:. n = 1

string, closed ends

if open end, like a tube?

L = n*/4n = must be an odd number

electrolytic:

*cathode negative

*anode positive

*anions go to anode*cations go to cathode

galvanic:

*cathode positive

*anode negative

*anions go to cathode

ideal gas law assume that molecular volumes and intermolecular attractive

forces are negligible.

>10.13

where n of medium = 1.5,

= and > b/c low index high index, bend towards normal

>10.14 this question is more about strongest reducing agent, b/c readily

lose octet

remember, reactivity increases downward (easier to remove e-) and leftward
