KINETICS - AS Flashcards
1
Q
factors that affect the rate of reaction
A
temperature
concentration
pressure
using a catalyst
2
Q
define activation energy
A
the minimum amount of energy required for a reaction to occur
3
Q
state the meaning of the term catalyst
A
chemically unchanged at the end of the reaction
increases the rate of reaction
4
Q
explain in general terms how a catalyst works
A
provides an alternative reaction pathway whilst lowering the activation energy
5
Q
Explain how a catalyst increases the rate of a reaction. Refer to the Boltzmann distribution in your answer.
A
A catalyst provides an alternative reaction pathway with a lower activation energy
More successful collisions result in increased rate of reaction
