pressure. The ME and the experimental results are close to each other in this region, while 2DME slightly overestimate the experimental data. In the mid-pressure region (10~1000 Torr), the rate coefficients continue to rise but at a slower rate compared to the low-pressure region, and all theoretical and experimental results are in good agreement. At high-pressure region (above 1000 Torr), the rate coefficients reach a plateau, where further increasing in pressure has little effect on the reaction rate. Our ME calculation slightly overestimates the experimental and the 2DME results in this region. Overall, it confirms the accuracy of our theoretical model and its ability to predict kinetics behavior under wide temperature and pressure conditions.
