Extracted text: The gas phase reaction A → B + C is to be carried out isothermally in a 20 dm’ constant voiume batch reactor, 2u moies of pure A is initially placed in the reactor. The reactor is well-mixed. a) If the reaction is first order; -ra= kCa with k 0,865 min', calculate the time necessary to reduce the number of moles A in the reactor to 0.2 mole? b) If the reaction is second order; -ra = k C.² with k= 2dm'/mol min. Calculate the time necessary to consume 19 moles of A?
