CHEM 112- FINAL EXAM QUESTIONS AND ANSWERS WITH COMPLETE SOLUTION
quickly - gases react more [slowly/quickly] than liquids
concentration, temperature, catalyst, diffusion rate - factors affecting reaction rates
reaction rate - the speed of a chemical reaction in molarity/second
change in concentration of B/change in time - average rate of appearance of B
instantaneous rate - the rate of reaction at a particular moment
initial rate - rate at time = 0
rate law - an equation that shows how the rate depends on the concentrations of reactants
K[A]^m x [B]^n - general form of a rate law
rate constant - the units of this can be found by dividing M/s by the units of concentration
zero - if a reaction is unchanged by concentration, it is this order
first - if the rate change is proportional to concentration change, the reaction is this order
second or greater - if rate change is exponential, the reaction is this order
does - the rate of a reaction [does/does not] depend on concentration
does not - the rate constant [does/does not] depend on concentration
first-order reaction - a reaction whose rate depends on the concentration of a single reactant raised to
the first power
ln[A] sub t = -Kt + ln[A] initial - the integ rate law
