Use Excel Flow Sheet to solve the resulted system of equations by Euler and R-K 4th order method and compare the two methods (Choose an appropriate time step) 2. Plot the two concentrations as a function of time. 3. Determine the concentrations at the new steady state conditions. rob.1 20 points) ** =- Solve numerically this system using excel flow sheet.
