Question
(a) Select all of the correct statements about reaction rates from the choices below.
The lower the rate of a reaction the longer it takes to reach completion.
Reactions involving very unstable combinations of chemicals have small rate constants.
Slow reactions can be speeded up by raising the temperature.
Reaction rates are determined by reactant concentrations, temperatures, and reactant stabilities.
Reaction rates increase with increasing temperature.
The rate of a slow step has more effect on the overall reaction rate than the rate of a fast step.
Reaction rates increase as concentrations of homogeneous catalysts increase.
