the rate of reaction
increases with increasing temperature
R is
the gas constant (8.314 J/mol⋅K)
A is
a constant called the frequency factor
Ea is
the activation energy/activation barrier
The exponential factor increases
with increasing temperature
activation energy(Ea) is
an energy barrier/hump that must be surmounted in order for the reactants to transform into products
frequency factor (A) is
the number of times that the reactants approach the activation barrier per unit time
The higher the activation energy
the slower the reaction rate (at a given temperature)
The exponential factor is
the fraction of the approaches that are successful in surmounting the activation barrier and forming products
The exponential factor decreases with
increasing activation energy
