The production of styrene from the dehydrogenation of ethylbenzene has the main reaction below. The process also generates by-products of benzene and toluene. Ethylbenzene may react with hydrogen to form toluene and methane: C6H5C2H5C6H5C2H3+H2 Using the attached process flow diagram, please (1) trace and describe the primary flow pathways for the main reactant, ethylbenzene, (bold pen) and product, styrene, (color pen), and (2) add the processing conditions to the output stream for the reactor R402 and the main product stream if the output stream from the reactor R402 is operating at 609C and 160kPa with a mass flow rate of 199,010kg/h and the main product stream is operating at 124.5C and 200kPa with a mass flow rate of 35,500 kg/h
