MCAT Gen Chem JB

TermDefinition
Delta G at Equilibrium 0
Delta G equation -RTlnK OR delta H - T delta S
Keq equation [product]/ [reactants]
K < 1 means Delta G is... positive; NON-spontaneous
Negative Delta G Spontaneous/ Exergonic
Delta H; Enthalpy Negative- release heat; exothermic Positive- requires heat; endothermic
Oxygen's oxidation Number -2
STP? 1 atm 273 K 1 mole of gas at STP is 22.4 L
Rate law k[reactants]^reactant coefficient
Positron positively charged electron
Arrhenius Acid/ Base Donates/ Accepts Protons
High Vapor pressure Boils easily; Low BP; low------------------------------->high strong intemolecular forces > heavy molecular weight > linear > bulky
Positive Reduction Potential means.... more easily reduced
Positive Cell voltage will proceed spontaneously
Delta G for electrochem Cell = -nFE where E is the cell voltage
Galvanic/ Voltaic Cell Anode is Negative (electrons go towards the positive cathode)
Electrolytic Cell Anode is Positive (electrons to towards the negative cathode)
State Functions are... pathway independent
Adiabatic rxn No heat exchange
Isochoric rxn Constant Volume
Change in Energy = q (heat) + Work where Work = -change in V * P external

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:

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.
