When the glass transition temperature equals f-sub-g over alpha-sub-f, the VFTH equation reduces to this equation.
When the glass transition temperature equals f-sub-g over alpha-sub-f, the VFTH equation reduces to this equation. One quantity in this equation is equal to the the square root of 8 kT over the product of pi and the reduced mass times Avogadro's number times the cross-section. The temperature dependence of the diffusion coefficient in a solid can be modeled using this equation. Another (*) quantity in this equation is equal to the product of the steric factor and the collision frequency, and has units of frequency for a first-order reaction. This equation states that the exponential of minus activation energy over RT times the pre-exponential factor is equal to the rate constant. For 10 points, name this equation which gives the temperature dependence of a reaction rate.
