The given question is a MATLAB question (Please give the MATLAB codes for each question).

1.a) A brine solution containing 0.2lb of salt/gallon of water is added at a rate of 5 gallons per minute to a tank with 1000 gallons of pure water. The volume in the tank is maintained at a constant volume of 1000 gallons with an overflow drain. Find the concentration change with time (upto 20min ) using Euler's Method and 4th order Runge Kutta Method dtdMS=10.005Ms Where Ms= mass of salt b) Find the conversion after 1 hour in a batch reactor for the reaction AR,dtdCA=3CA0.5litre.hrmolCA0=1mol/litre(att=0) using Euler's Method and 4th order Runge Kutta Method
