A line graph titled Arrhenius learned. The horizontal axis is labeled 1/T (1/K) and ranges from 0.00210 to 0.00235. The vertical axis is labeled ln(k) and ranges from -8.75 to -7.00. The graph shows a linear trend with data points plotted along a straight line, indicating a negative correlation between the natural logarithm of the reaction rate and the inverse temperature.Learned Arrhenius relationship obtained from the PINN, showing the natural logarithm of the reaction rate plotted against the inverse temperature . The linear trend indicates that the network successfully recovered Arrhenius-type thermal activation behavior from the short-term dataset
