Answer
The collision model is based on the concept that molecules must collide to react.
a) a larger activation energy means a lower rate of reaction
b) a higher temperature means a higher rate of reaction
c) a higher frequency of collisions means a higher rate of reaction
d) a higher frequency of correctly oriented collisions means a higher rate of reaction.
Work Step by Step
a) a higher activation energy makes it harder for the molecules to react because it is less likely that the molecules will react when they collide.
b) a higher temperature makes the molecules move faster, and this increases the chances of collisions
c) a higher frequency of collisions gives more opportunities for reactions to occur
d) a higher frequency of correctly oriented collisions means that the molecules are more likely to react when they collide.
