the question please

A +B K1 + R 1. For irreversible series-parallel reactions R+B- , 1 mole of A and 1 mole of B are rapidly mixed together in a batch reactor, and the initial concentration of R and S is zero. When 0.8 mole of B is consumed, 0.2 mole of S is present in the mixture. What would be the maximum concentration of R that can be achieved in this reaction system? A +B -R R + B -2+ S 0.8 1.2 0.8 Batch or plug flow CRO = Cso = 0 1.4 0.6 0.4 CAO 0.4 0.6 7 1/ 1.6 0.4 10.8... Amount of B used alk, = 1.5. -ACB . = 0.2 CAO 1.8 0.2 0.2 0.4 0.6 0.8 XA = 1 - - CA CAO
