Question

2.) After the conversion above nearly reaches equilibrium, the mixture is pumped to a distillation column where form C is desired. The feed stream is 34% A, 24% B and 42% C by weight. The bottom exit stream is 10% A 20% B and 70% C, while the top exit stream only contains 20% C by weight and flows at 20 kg/hr. (a - 2 points) Arrange this information into a system of linear equations and assume the process runs at steady-state (In - Out = 0). (b - 2 points) Convert your system of equations into matrix form and use Gauss-Jordan Elimination to solve for the mass flow rates of each exit stream and the remaining composition of the top exit stream in terms of %A and %B by weight. (c- 2 points) Show that you obtain the same result using Cramer's Rule.

NEED help. Have to be done by hand and MATLAB. please help
