Second-Order Reaction
Chemical Kinetics & Catalysis
L/(mol·s)
A reaction whose rate depends on the square of one concentration or on the product of two concentrations.
1/[A] = 1/[A]₀ + kt
Selectivity
Chemical Kinetics & Catalysis
Dimensionless
The ability of a catalyst to direct a reaction towards one particular product among several possible ones.
selectivity = desired product / total product
Steady-State Approximation
Chemical Kinetics & Catalysis
mol/L
The assumption that the concentration of a reactive intermediate stays essentially constant because it is consumed as fast as it is formed.
d[intermediate]/dt ≈ 0
Steric Factor
Chemical Kinetics & Catalysis
Dimensionless
The fraction of sufficiently energetic collisions that also have the correct spatial orientation for reaction.
p = A / Z
