Step 1

Let the basis of the calculations be 1 mole of CO2 fed to the reactor. Since there is 70% conversion of CO2, moles of CO2 reacted and left are:

Step 2

From the stoichiometry of the given reaction, 1 mol CO2 reacts with 4 mol H2 and forms 2 mols H2O and 1 mol CH4. So, when 0.70 mol CO2 is converted, it needs 2.8 mols of H2 to form 1.4 mols H2O and 0.7 mol CH4.

Step 3

Now, prepare the inlet-outlet enthalpy table for the given process and tak...
