一、H２和O２反应例１如图１所示，烧瓶倒置在水银槽中，在烧瓶中装有H２和O２，H２和O２的物质的量成一定比例。开始时烧瓶内外液面相平，温度为３５０K。烧瓶中两电极在外加电源的作用下发生火花放电。由于有催化剂，H２和O２能完全反应，反应放出热量。当瓶中气体的温度保持 First, H2 and O2 Reaction Example 1 As shown in Figure 1, the flask was inverted in a mercury tank, and H2 and O2 were contained in the flask, and the amount of H2 and O2 was in a certain amount. At the beginning, the inside and outside of the flask were flat and the temperature was 350K. The two electrodes in the flask underwent spark discharge under the action of an external power supply. Due to the catalyst, H2 and O2 react completely and the reaction gives off heat. When the temperature of the gas in the bottle is maintained
