Mass Transfer Problem. could you please help in the matlab code. Im kind of confused.

Estimate the gas phase diffusion coefficient of ammonia (NH3) in Methanol at 1.0 atm and 373K by making use of Brokaw equation in the calculations. The dipole moment (Hp) for NH3 is 1.46 debye, and the liquid molar volume at the normal boiling point (V) is 25.8 cm /mole and To=239.7 K. The dipole moment (Hp) for Methanol is 1.70 debye. and the liquid molar volume at the normal boiling point (Vb) is 59.2 cm3/mole and Th=337.85 K. Assume A: NH3, B: Methanol 1. Calculate the mutual diffusion coefficient DAB at T=373 K and 1.0 atm (Hand calculation) 2. Using MATLAB, study the influence of system temperature and pressure on the diffusion coefficient. Range of the study for system temperature is T [273-373] K with 20 degrees step size and for system pressure is P[1-12) atm with step size of 0.5 atm 3. Submit your solution in part 1 as PDF file, Groupl_handcalculations.pdf 4. Submit your solution in part 2 as .m file, Group1_DAB_Brokaw.m 5. Comment on your analysis of pressure and temperature influence on Das at the end of the PDF file. Hint 1: DA (300 K, 2.0 atm)=0.0738 cm/s. Hint 2: The final graph should look like this: 0.25 213 295 313 02 0.15 353 -373 PAB Ins/ 0.1 0.05 2 12 6 10 P. Hint 3: Use the following variables definition when you write your MATLAB script file: T_sys-[273:20:373]; XK P_sys-[1..5:12]; Xatm % Material A: NH3 MW_A-17.031; % g/mol mu_A-1.46; % updipole moment, Debye Vb_A-25.8; % See table 24.4 Welty 5th ED Tb_A-239.7; % normal boiling point, K sigma_A=2.9; % NH3, collision diameter, Lennard-Jones parameter % Material B: Methanol MW_B=32.04; % g/mol Methanol mu_B-1.70; % Methanol up=dipole moment, Debye Vb_B=59.2; % see p 561 ex 2 welty 6th Ed TB_B=337.85; % normal boiling point, K sigma_B=3.585; % methanol, collision diameter, Lennard-Jones parameter
