Kinetics
This is the term for the minimum energy that reacting molecules must have in order to successfully collide and form products.
What is the activation energy?
This is the term for a function the measures the total energy change of a system at constant pressure, often equivalent to the heat absorbed or released from a reaction.
What is Enthalpy?
This type of equilibrium occurs when a chemical reaction proceeds at the same rate in both the forward and reverse directions.
What is chemical equilibrium?
These are the six strong acids commonly recognized in chemistry.
What are: HCl, HBr, HI, HNO3, HClO4, and H2SO4?
Most mornings, Professor Waitt needs to drink this to teach class.
What is coffee?
This is the overall order of a reaction whose rate law is rate=k[A]2/3[B]2.
What is 8/3?
This is the thermodynamic quantity that measures the disorder or randomness of a system.
What is entropy?
If the reaction quotient Q is greater than the equilibrium constant K, this is the direction the reaction will shift.
What is shift to the left (toward reactants)?
Compounds that typically end with this polyatomic group are considered to be strong bases.
What is OH-?
Professor Waitt has signs outside his office. If the sign is white and he is not in class, he is doing this activity.
What is walking?
This type of substance or material increases the rate of a chemical reaction by providing an alternative pathway with a lower activation energy.
What is a catalyst?
This numbered law of thermodynamics states that the entropy of the universe always increases for any spontaneous process.
What is the second law of thermodynamics?
For the equilibrium BaF2(s)<=>Ba2+(aq)+2F−(aq), this is the expression for the equilibrium constant.
What is K=[Ba2+][F−]2?
or
What is Ksp=[Ba2+][F−]2?
This is the name of the process in which two water molecules react to form \H3O+ and OH− ions in pure water.
What is the autoionization of water?
According to the sweaters he wears, this deep rich color is Professor Waitt's favorite.
What is Maroon/Red?
These are the three main postulates of collision theory that must be satisfied for a chemical reaction to occur.
What are: (1) particles must collide, (2) collisions must have sufficient energy (activation energy), and (3) particles must collide with proper orientation?
These are the signs of ΔH, ΔS, and ΔG for an exothermic process in which the disorder of the system increase at low temperature.
What are: ΔH<0 (negative), ΔS>0 (positive), and ΔG<0 (negative)?
This describes the relationship between spontaneity and the size of the equilibrium constant K for a reaction.
What is: if a reaction is spontaneous ΔG∘<0, then K>1; if a reaction is nonspontaneous ΔG∘>0\, then K<1?
In a buffer solution containing HCH3COO (acetic acid) and CH3COO− (acetate ion), this component will react with added OH− to resist a pH change.
What is HCH3COO?
What is take attendance?
For the reaction 2NO2 → 2NO+O2, if the rate of disappearance of NO2 is 0.020 M/s, this is the rate of formation of O2.
What is 0.010 M/s?
For the reaction N2(g)+3H2(g)<=>2NH3(g), the direction the reaction will shift total pressure is decreased.
What is shift to the left (toward reactants)?
This is the name of the point on a phase diagram where solid, liquid, and gas phases are all in equilibrium with each other.
What is the triple point?
This is the expected pH at the equivalence point when a strong acid is titrated with a weak base.
What is less than 7 (acidic)?
Despite repeated reminders, this common error on exams and labs drive professor Waitt crazy.
What is forgetting units and not writing answers with correct sig figs!
