Describe how the four major factors influence the rate of a
chemical reaction.
(a) concentration of reactants
As the concentration of reactants increases, the number of
collisions per unit time ---Select--- increase decrease
, and the reaction rate ---Select--- increases decreases
.
(b) frequency factor
The frequency factor is a measure of molecular obstruction. More
obstruction in a molecule leads to a ---Select--- higher
lower frequency factor, which ---Select--- increases
decreases the rate constant, resulting in ---Select---
an increased a decreased overall reaction rate.
(c)...
