Rates of reaction Flashcards
1
Q
Define rate of reaction
A
The charge in concentration per unit time of any one reactant or product
2
Q
Explain the term activation energy
A
The minimum energy that colliding particles must have in order for effective collisions to occur.
3
Q
Define homogeneous catalyst
A
When the catalyst and the reactants are in the same phase
4
Q
Define heterogeneous catalysis
A
When the catalyst and the reactants are in different phases.
5
Q
Define auto catalysis
A
When the products formed in a reaction acts as a catalyst to the reaction.
6
Q
What is a catalyst
A
Is a substance that alters the rate of a chemical reaction but is not consumed in the reaction.
7
Q
How can a catalyst lower the of activation energy in a reaction
A
Provides alternative pathway for reaction
