- The activaton energy is the minimum energy required
- It determines the rate of reactions
ARHENIUS EQUATION
k = Ae^-Ea / RT
k = Rate Constant
Ea = Activation Energy
R = Universal Gas Constant
T = Temperature (in Kelvin)
A = Pre exponential or Frequency factor

- A + B ---> Products
- Rate Law = k[A]^m [B]^n
- Catalyst speed up reactions by lowering the activation energy barrier
- Positive Catalyst speed up reactions
Negative Catalyst slows down reactions
