Q.2 ( 8 pts) The elementary, reversible, liquid-phase reactions A+BC is to be cartied oue adiabatically in a set of tubular reactors packed with resin and arranged in series. The feed consists of mole fraction of 0.25A,0.25B and 0.5 inert at 300K. There are interstage coolers to cool reaction streams to 300K at each stage. Find the number of reactors needed to obtain exiting conversion above 50% CP=2J/mol.K,CPH=5J/mol.K,CPC=7J/mol.K,CP1=1.5J/mol.K
