Kinetics Flashcards
1
Q
Collision theory
A
Physical contact,
Correct orientation
Sufficient kinetic energy
2
Q
Effects of a reactant on increasing rate of reaction
A
Increasing concentration
Increasing temp
Decreasing particle size
3
Q
Greater the Ea
A
Slower the reaction rate
4
Q
Maxwell-Boltzmann
A
As temperature increases, fraction of collisions with required Ea increases
5
Q
Catalysts
A
Increase rate of chemical reaction without BEING CHEMICALLY CHANGED
6
Q
End of MB graph
A
Catalysts lower the minimum kinetic energy needed for reactants to collide, greater number of particles possess minimum energy and rate increases
7
Q
Experimental procedures for measuring rates of reactions
A
- Mass or volume changes for gaseous reactions
- change in pH for reactions involving acids and bases
- change in conductivity
- use of a spectrophotometer for reactions INVOLVING COLOR CHANGES
8
Q
Activation energy
A
The minimum amount of energy required to bring about a chemical reaction
