Pressure-Based Rates By Theory Alone

Chemical Kinetics: Method reveals how pressure affects reaction rates without need for experimental data

Keywords: kinetics, pressure-dependent reaction

Researchers have devised a new theoretical method for calculating the speediness of reactions whose rates depend strongly on pressure. In the past, such calculations have always needed at least a bit of empirical help, but the new technique does the job purely theoretically, with no experimental data needed.

The speed of some reactions depends mostly on temperature, and rates of those reactions could in many cases already be determined theoretically without experimental assistance. But rates . . .
