A proposed mechanism is: C4H9Br --> C4H9^+ + Br^– (slow)
C 4H9^+ + H2O --> C4H9OH2^+ (fast)
C4H9OH2^+ + H2O --> C4H9OH + H3O^+ (fast)

i. What are the mechanism’s intermediates?
ii. Write the reaction’s overall balanced equation.

iii. Write the correct rate law, based on the given mechanism.

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.

The solid xy decomposes into gaseous x and y: xy(s) m x(g) + y(g) kp = 4.1 (at 0 °c) if the reaction is carried out in a 22.4 l container, which initial amounts of x and y will result in the formation of solid xy?
