Answer :
Final answer:
The correct temperature used for gases to react, noted in the provided material, is closest to 10 ℃. However, chemical processes often double reaction rates with a rise in temperature, and some reactions are performed at much higher temperatures like 1000 ℃ or 850 K.
Explanation:
The question seems to inquire about the temperature used for gases to react during a chemical experiment. According to the provided reference material and the concept that for many chemical processes reaction rates approximately double with every 10 ℃ rise in temperature, we understand the importance of temperature in chemical reactions.
The provided solution shows the conversion of temperature to kelvins, pointing to a specific temperature of 25 ℃ (298 K) used for calculations or reactions, which matches our options as close to 10 ℃ (option 1).
Chemical reactions, like the decomposition of carbon dioxide into CO and O₂ or the chlorination of methane to form carbon tetrachloride, can occur at much higher temperatures specified as 1000 ℃ and 850 K respectively.
