A100. kmol/hr stream that is 96.0 mole% carbon tetrachloride (ccl4) and 4.0 mole% carbon disulfide (cs2) is to be produced from the bottom of a distillation column. the feed to the column is 83.0 mole% ccl4 and 17.0 mol% cs2 ,and 2.5 mol% of the ccl4 entering the column is recovered in the overhead stream leaving the top of the column. what is the mole fraction of ccl4 in the stream that is leaving the top of the distillation column?

Effect of rotenone and antimycin a on electron transfer rotenone, a toxic natural product from plants, strongly inhibits nadh dehydrogenase of insect and fish mitochondria. antimycin a, a toxic antibiotic, strongly inhibits the oxidation of ubiquinol. (a) explain why rotenone ingestion is lethal to some insect and fish species. (b) explain why antimycin a is a poison. (c) given that rotenone and antimycin a are equally effective in blocking their respective sites in the electron-transfer chain, which would be a more potent poison? explain.
