| Term | Definition |
|---|---|
| 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 |
