please rewrite this:
To study the impact of temperature and stress on reactivity, we analysed the decomposition rate data using Eq. (1) as a 3D surface. We also used fits to the logarithm of the rate to prevent bias towards higher rates in the 3D fits. The 3D fits are shown in Fig X and Y for Fe and Fe3¬O4 respectively. The 3D surfaces were used to calculate ΔV*, Ea, and A values over the entire range of temperatures and pressures studied (Table 1). Unlike the 2D plots, the 3D fitting method did not capture the change in parameters with temperature and pressure. However, compared to the 2D fits, the 3D fits generally resulted in reduced uncertainties in all three parameters in the Bell model.
