using matlab and also balancing on a paper and degree of freedom

Q2. Ethanol is produced commercially by the hydration of ethylene: C2H4+H2OC2H5OH Some of the product is converted to diethyl ether in the side reaction 2C2H5OH(C2H5)2O+H2O The feed to the reactor contains ethylene, steam, and an inert gas (call it 1). A sample of the reactor effluent gas is analyzed and found to contain 43.3 mole \% cthylene, 2.5% cthanol, 0.14% ether, 9.3% inert gas and the balance water. a) Take as a basis 100 mol of effluent gas, draw and label a flowchart, and do a degree-offreedom analysis based on extent of reaction to prove that the system has zero degrees of freedom. b) Form a system of linear equations and solve it using MATL.ABE to find all the unknowns in the problom
