This value appears in the numerator in Black's equation, which is used to calculate it for self-diffusion in pure metals.
This value appears in the numerator in Black's equation, which is used to calculate it for self-diffusion in pure metals. It is usually determined experimentally by taking the slope of the line that appears on the graph plotting the log of k against one over temperature. A negative value of this quantity appears in the exponential divided by RT in the Arrhenius equation. For 10 points, name this value that is lowered by catalysts, and is equal to the minimum energy that molecules must have in order to react.
