Choose all appropriate equations for the calculation of needed reaction time in an ideal tubular-reactor. (2 points) the reaction: A+B>P second-order elementary reaction 0 : starting; c: concentration; i: limiting component; n : molar flow; k reaction rate coefficient; X : conversion; r : stoichiometrically independent specific reaction rate; time; V : volumetric flow of reaction mixture, which is constant Select one or more: a. t=cA0cArdcA b. t=(i)cij0XkcAcBdX C. t=(i)Vn;0XrdX d. t=(i)niv0XkcAcBdX e. t=(i)kci00XcAcBdX
