This non-numerical quantity appears in the numerator of Black's equation for calculating mean time to failure. Marcus theory of electron transfer involves a parabolic approximation of this quantity. A plot of the natural log of k versus one over T has a slope equal to this quantity divided by the gas constant. The rate constant equals the frequency factor times e raised to the negative value of this quantity divided by RT in the Arrhenius equation. For 10 points, name this quantity that is lowered by catalysts and is the minimum energy needed for chemical reactions to occur.
