Chapter 10- Reaction rates and equilibrium Flashcards
1
Q
Define rate of a chemical reaction
A
The rate of a chemical reaction measures how fast a reactant is being used up or how fast a product is being formed.
2
Q
Define homogenous catalyst
A
A homogenous catalyst has the same physical state as the reactants.
3
Q
Define heterogenous catalyst
A
A heterogenous catalyst has a different physical state from the reactants.
4
Q
Define adsorbtion
A
When reactant molecules are weakly bonded onto the surface of the catalyst.
5
Q
Define desorption
A
The process by which the product molecules leave the surface of the catalyst.
