Determination of Activation and Reaction Volumes of Polar and Isopolar Reactions Using Rule of Noncrossing of Curves ln(kP/kP=1) = f(P)

Key Points

• This research aims to derive an equation for calculating activation and reaction volumes from rate constants under high pressure.
• Collected data on polar and isopolar reactions at atmospheric pressure and 1000 bar.
• Analyzed the influence of high hydrostatic pressure on rate constants.
• Derived an equation for activation and reaction volumes using rate constants at two pressures.
• The derived equation allows determination of activation volume from just two rate constant values.
• Differences between experimental and calculated activation volumes are within standard error limits.
