# Chem 202 Test 2

-E cell (harder or easier to remove e-) harder to remove an electron than H More likely to be oxidized
+E cell (harder or easier to remove e-) easier to remove electron than H More likely to be reduced
Nernst Equation Ecell= Ecell - 0.059/n x log (products/reactants)
- Delta G (spontaneous or non) spontaneous
Delta G = -n F Ecell (kJ/mmol or J/mol) J/mol
R= 8.3145
-RTlnK=-nFEcell Ecell= RTlnK/nF
k (0 order) mol/Lxs
k (1 order) 1/s
k (2 order) L/molxs
k (3 order) L2/mol2xs
1st order (integrated rate law) ln [a] = -kt + ln [a0]
half life- first order t1/2= ln2/k
2nd order (integrated rate law) 1/[a] = kt + 1/[a0]
half life- second order t1/2= 1/k[a]
zero order (integrated rate law) [a] = -kt + [a0]
half life- zero order t1/2= [a]/2k
k (positive/negative slope) - 1st order negative slope
k (poisitve negative slope) - 2nd order positive slope
k (positive negative slope) - 0 order negative slope
Focus on large or small concentrations? small
rate determining step first slow reaction
Arrhenius Equation lnk = - (Ea/R) (1/T) + ln[A]
m (Arrhenius Equation) = -Ea/R
Two Point Form ln(k2/k1) = -Ea/R (1/T2-1/T1)
If atomic number matches the element but the mass # is higher Beta Emission
When is neutrino a product Beta Emission and electron capture
If atomic # matches element but the mass # is lower Positron emission
When is an antineutrino released In positron emission
if atom has correct # of protons and same mass as the periodic table electron capture (gamma)
when above Bismuth alpha-decay
Kinetics is always what order first
Rate law of kinetics N= Ni e^-kt or lnN = -kt + ln Ni

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
