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
