AB  - Sensitivity analyses of rate constants for chemical kinetics of the pyrolysis 
      reaction are essential for the efficient valorization of plastic waste into 
      combustible liquids and gases. Finding the role of individual rate constants can 
      provide important information on the process conditions, quality, and quantity of 
      the pyrolysis products. The reaction temperature and time can also be reduced 
      through these analyses. For sensitivity analysis, one possible approach is to 
      estimate the kinetic parameters using MLRM (multiple linear regression model) in 
      SPSS. To date, no research reports on this research gap are documented in the 
      published literature. In this study, MLRM is applied to kinetic rate constants, 
      which slightly differ from experimental data. The experimental and statistically 
      predicted rate constants varied up to 200% from their original values to perform 
      sensitivity analysis using MATLAB software. The product yield was examined after 
      60 min of thermal pyrolysis at a fixed temperature of 420  degrees C. The predicted rate 
      constant "k(8)" with a slight difference of 0.02 and 0.04 from the experiment 
      revealed 85% oil yield and 40% light wax after 60 min of operation. The heavy wax 
      was missing from the products under these conditions. This rate constant can be 
      utilized to maximize the commercial-scale extraction of liquids and light waxes 
      from thermal pyrolysis of plastics.
