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 |
