 Please answer the question from the second paragraph. Acetaldehyde is synthesized

Please answer the question from the second paragraph.

Acetaldehyde is synthesized by the catalytic dehydrogenation of ethanol: C2H5OH CH3CHO + H2 Fresh feed (pure ethanol) is blended with a recycle stream (95 mole% ethanol and 5% acetaldehyde), and the combined stream is heated and vaporized, entering the reactor at 280C. Gases leaving the reactor are cooled to condense the acetaldehyde and unreacted ethanol. Off-gas from the condenser is sent to a scrubber, where the uncondensed organic compounds are removed and hydrogen is recovered as a by-product. The condensate from the condenser, which is 45 mole% ethanol, is sent to a distillation column that produces a distillate containing 99 mole% acetaldehyde and a bottoms product that constitutes the recycle blended with fresh feed to the process. The production rate of the distillate is 1000 kg/h. The pressure throughout the process may be taken as 1 atm absolute. If the reactor effluent is at 360C, calculate the heat transferred to or from the reactor. Hint: Go back to previous running homework problems to find reactor feed and effluent flow rates (or solve for them again now!).
