126. Solving a chemistry problem

32. For the reaction R←k1-A-k2→S with constants k1=2 s-1, k2=0.7 s-1, it is required to determine:
1) the number of moles of products R and S formed per 1 mole of the introduced reagent A for the plug-and-play reactor and the ideal mixing reactor, if the degree of conversion of the initial reagent for both reactors is 0.95;
2) the residence time required to achieve the specified degree of conversion in each type of reactor.
