A two-step chemical reaction takes place with through the following mechanism: Step 1: NO(g) + Br2(g) ↔ NOBr2(g) (fast)
Step 2: NOBr2(g) + NO(g) → 2 NOBr (g) (slow)

The proposed rate law for the overall reaction is: rate = k[NO][Br2]

A. Write the equation for the overall reaction, including states of matter.

B. Identify a catalyst (if possible).

C. Identify any/all intermediates (if possible).

D. Is this two-step mechanism consistent with the proposed rate law above? Show any/all substitution
steps if needed.

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.
