Q2. Consider a batch reactor where the reaction is: A+BC. Reactant B is in excess and the reactant A is the limiting reactant, the reaction is first order with respect to A. The reaction rate constant is given as: k=104exp[104/RT]51. Initially the reactor is charged with 1000kg of A ( 2381 moles) and 200kg of B ( 50000 moles). Addditional data: CpA=43.8cal/mol.kCpB=16.8cal/mol.kCpc=54cal/mol.KHtA=10000cal/molHtB=68000cal/molHtC=82000cal/mol Determine the time required to achieve 50% conversion
