Kinetics Flashcards
1
Q
Give the equation for rate of a reaction
A
Change in concentration of reactant or product / time taken
2
Q
What must particles have to react?
A
E ≥ Ea
Correct orientation
3
Q
Define activation energy
A
The minimum energy particles must have to react when a collision occurs
4
Q
Give features of the Maxwell-Boltzmann Distribution Curve
A
Begins at origin
Emp when no. of particles is highest
Area represents no. of particles
Asymptotic to x axis
5
Q
What is the effect of increasing concentration on rate of reaction?
A
Increases - more molecules so larger area where E ≥ Ea
6
Q
What is the effect of adding a catalyst on rate of reaction?
A
Increases - lower Ea so more molecules have E ≥ Ea
