Energy and Rates of Reaction Flashcards
1
Q
Kinetic Energy
A
- energy of motion
2
Q
Temperature
A
- measure of average kinetic energy
- higher temp means faster particles
3
Q
Thermal Energy
A
- depends on amount of particles and their temperature
4
Q
Heat
A
- transfer of kinetic energy from substance with higher temp to substance with lower temp
5
Q
Determining Reaction Rates
A
Reaction rate = [final] - [initial] / Tfinal - Tinitial
6
Q
Effective Collision
A
- must have proper orientation
- must have sufficient energy
- activation eng is the min amount of eng required for a reaction to occur
7
Q
Rate Laws
A
rate = k[A]m[B]n
k = rate constant
m, n = orders
8
Q
Zero Order
A
- reaction where reaction rate is completely independent of reactant concentration
9
Q
Rate Determining Step
A
- slowest elementary step (highest ea)
- an overall reaction can occur no faster than the slowest of its elementary steps
