The following reactions occur at 500 K. Arrange them in order of increasing tendency to proceed to completion (least complete most complete). 1. 2NOCl <===> 2NO + Cl2 Kp = 1.7 x 10-2 2. 2SO3 <===> 2SO2 + O2 Kp = 1.3 x 10 -5 3. 2NO2 <===> 2NO + O2 Kp = 5.9 x 10 -5 Group of answer choices

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.
