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.
Reaction rates are determined by reactant concentrations, temperatures, and reactant stabilities.
Reaction rates decrease with increasing temperature.
A balanced chemical reaction is necessary to relate the rate of reaction to the concentration of a reactant.
The rate of a fast step has more effect on the overall reaction rate than the rate of a slow step.
Fast reactions can be slowed down by lowering the temperature.
Reactions involving very unstable combinations of chemicals have small rate constants.
