4.5 Collision Theory and Rate Constants

Question 1

Collision Theory: What must happen for a reaction to take place?

Answer 1

#1 Collision
-An increase in temperature = A raise in collision frequency
#2 Proper orientation
#3 Sufficient energy
-An increase in temperature = A raise in high energy collisions.

Question 2

Arrhenius Equation

Answer 2

k = Ae^ Ea/RT
k=rate constant
Ae=frequency
Ea=activation energy
R=gas constant (8.315)
T=temperature

As temp rises, the rate constant increase
As activation energy rises, the rate constant decreases
