What is -Ea/R?
Describe adiabats, isotherms, and isochors

This order of reaction has a half life independent of initial concentration.
What is first order
This equation describes all boundaries in a phase diagram (you must give equation)
Clapeyron equation, dp/dT=dS/dV

q and w
Which step is always exothermic: R -> I, I -> P, R -> P
I->P
This is the variable that corrects for non-ideality of solutions. What does the sign of the variable indicate?
What is xi, positive is endothermic, negative is exothermic
What's the difference between the steady state approximation and pre-equilibrium
What is steady-state involves all intermediate steps, pre-equilibrium is just the equilibrium steps
Ideal dilute solutions follow Henry's law which states the vapor pressure of the solute equals what 2 quantities.
What is mole fraction and constant, K?
Which quantity is larger Cp or Cv and why?
Cp, constant pressure means no work and less energy leaving the system
This theory describes how first order kinetics are applicable to unimolecular reactions.
