A liquid-phase reaction A>B+C is second-order in A with a rate constant of 0.01 L/ (mol.s) at 100C. The initial concentration of A in the feed mixture is 25mol/L. If the reaction is carried out in a batch reactor and the conversion of A is 80%, then the time (min) required for this reaction at 100C is most nearly: A. 0.27 B. 100 C. 16 D. 24 E. 1.7
