Distillation using mccabe-thiele method. a rectification column is fed 100 kg mol/h of a mixture of 50 mol % benzene and 50 mol % toluene at 101.32 kpa abs pressure. the feed is liquid at the boiling point. the distillate is to contain 90 mol % benzene and the bottoms 10 mol % benzene. the reflux ratio is 4.52: 1. calculate the kg mol/h distillate, kg mol/h bottoms, and the number of theoretical trays needed using the mccabe-thiele method.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

ok whats the question if not i cannot you i need question and need a thing to answer
