Use the Arrhenius equation for diffusion: \[ D = D_0 \exp\left(-\frac{Q_d}{RT}\right) \]Where:- \(D\) is the diffusion coefficient.- \(D_0\) is the pre-exponential factor.- \(Q_d\) is the activation energy.- \(R\) is the gas constant (\(8.314 \, \text{J/mol} \cdot \text{K}\)).- \(T\) is the temperature in Kelvin.
