Naïve hard-sphere theory predicts that these values are equal to the product of the cross-section and average relative speed, though that incorrectly predicts that this value is proportional to the square root of the temperature.
One method of measuring these constants involves shocking a system out of equilibrium and measuring the relaxation time. Stopped-flow experiments can be used to measure this quantity, which is found from the x-intercepts of tangent lines on a Chevron plot. Naïve hard-sphere theory predicts that these values are equal to the product of the cross-section and average relative speed, though that incorrectly predicts that this value is proportional to the square root of the temperature. An equation commonly used to calculate this value states that it's proportional to the steric factor and collision frequency, and it is proportional to (*) the exponential of the activation energy. This value's units are dependent on the order of the reaction it is describing, and can be calculated from the Arrhenius equation. For 10 points, name this constant describing the speed of a reaction.
