CHEM134 Final EXAM WITH ANSWERS |\ |\ |\ |\
instantaneous dipole - CORRECT ANSWERS ✔✔a temporary |\ |\ |\ |\ |\ |\ |\
change in charge distribution
|\ |\ |\
volatility - CORRECT ANSWERS ✔✔substance's tendency to
|\ |\ |\ |\ |\ |\ |\
vaporize
frequency factor (in the Arrhenius Equation) - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔Number of times the reactants approach the|\ |\ |\ |\ |\ |\ |\ |\
activation barrier per unit time |\ |\ |\ |\
elementary step - CORRECT ANSWERS ✔✔A step within the
|\ |\ |\ |\ |\ |\ |\ |\ |\
reaction mechanism, which cannot be broken down into smaller

steps. The molecularity of the step can be linked to a rate law (i.e.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
first order, second order, zero order)

|\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔the relationship between products and reactants of a
|\ |\ |\ |\ |\ |\ |\ |\
reaction at equilibrium
