The correct Answer is:
To analyze the statements provided in the question, we will evaluate each statement step by step. ### Step 1: Evaluate Statement-I **Statement-I:** "Extraction of iron metal from iron oxide ore is carried out by heating with coke." - The extraction of iron is commonly done from iron oxide ores, primarily hematite (Fe₂O₃) or magnetite (Fe₃O₄). - The process involves heating the ore with coke (a form of carbon) in a blast furnace. - While coke is indeed used in the extraction process, it is important to note that a flux (like calcium carbonate) is also added to help remove impurities as slag. - Therefore, while the statement is partially true, it is misleading as it does not mention the role of flux. **Conclusion for Statement-I:** This statement is misleading and can be considered false due to the omission of important details. ### Step 2: Evaluate Statement-II **Statement-II:** "The reaction Fe₂O₃ (s) → Fe (s) + 3/2 O₂ (g) is a spontaneous process at standard condition." - The reaction described involves the reduction of iron(III) oxide (Fe₂O₃) to iron (Fe) and oxygen (O₂). - This reaction is not spontaneous under standard conditions. In reality, Fe₂O₃ requires a significant amount of heat to reduce to iron, and it typically occurs at high temperatures (around 800-1000 °C). - The reduction of Fe₂O₃ to Fe involves intermediate steps, where Fe₂O₃ is first reduced to FeO before finally yielding iron, which also requires heat. - Therefore, the reaction as stated does not occur spontaneously at standard conditions. **Conclusion for Statement-II:** This statement is false as the reaction is not spontaneous under standard conditions. ### Final Conclusion Both statements are false. ### Answer: Both Statement-I and Statement-II are false.
