Term | Definition |
Kinetic Energy Equation | KE=1/2mv^2 |
First Law of Thermodynamics | Energy of Universe is Constant |
Second Law of Thermodynamics | For any Spontaneous Process, the entropy of the universe increases |
Third Law of Thermodynamics | The entropy of a perfect crystal at absolute temperature is Zero |
dE=q+w | q=heat energy (MCdT) w=work energy (-PdV) |
Specific Heat Capacity | Heat required to raise temp of 1 gram of substance by 1 degree C |
Molar Heat Capacity | Heat required to raise temp of 1 mole of substance by 1 degree C |
Calculate quantity of heat released or absorbed | q=MCdT |
Calculate Work W=-PdV | dV = volume, P=external pressure |
ΔH = ΔE + PΔV | change in enthalpy/heat |
If ΔH > 0? | Endothermic |
if ΔH < 0? | Exothermic |
Standard enthalpy change | ΔHProducts - ΔHReactants |
Particles-most freedom to least freedom | Translational, Rotational, Vibrational |
Gases can be condensed by | Decreasing temperature or increasing pressure |
A reaction is spontaneous if | ΔG < 0 (Entropy of universe increases) |
Standard Enthalpy Change for a reaction | ΔSrxn = Sproducts Sreactants |
Free Energy Changes in Chemical Reactions | ΔGrxn = ΔHrxn TΔSrxn |
