Ch4 and o2 react to form hcho and h2o with a catalyst. the reactants also react to form co2 and h2o under the same conditions. for a basis of 100 mol feed/s and equimolar feed of reactants: i) write the two balanced competing reactions in the reactor; ii). draw and label a flowchart and use a degree-of-freedom analysis based on extents of reaction to determine how many process variables must be specified to calculate the remaining variables; iii). derive expressions for the product stream component flow rates in terms of the extents of the two reactions; iv). calculate the molar composition of the reactor output stream and the selectivity of hcho relative to co2 if the fractional conversion of methane is 0.8 and the fractional yield of hcho is 0.75.
