Description

Calculates the effects of temperature on decomposition rates according to the Arrhenius equation.

Usage

1
fT.Arrhenius(Temp, A = 1000, Ea = 75000, Re = 8.3144621)

Arguments

Temp

A scalar or vector containing values of temperature (in degrees Kelvin) for which the effects on decomposition rates are calculated.

A

A scalar defining the pre-exponential factor.

Ea

A scalar defining the activation energy in units of J mol^-1.

Re

A scalar defining the universal gas contant in units of J K^-1 mol^-1.

Value

A scalar or a vector containing the effects of temperature on decomposition rates (unitless).
