4. In multiple overall reaction (OR) systems, certain linear combinations (as above) of some of the ORs produce the other ORs. In other words, not all are independent. In fact, only an independent set is needed for kinetic or equilibrium analysis. Thus, consider the set of the following 4 ORs in the process of methane stem reforming: Overall Reaction OR : CH4+H,0 = C0+3H, ORY: CO + H20 = CO2 + H2 OR3: CH4 + 2H20 2 CO2 + 4H2 OR : CH4+CO2 = 200+2H2 Show, e.g., that the last two ORs can be produced by linearly combining the first two, or indeed, the other way around. Hence reduce this system to an independent set of ORs. Does this agree with the formula: R=n-e, where n is the number of chemical species, and e is the number of elements? (10 points).
