為什麼這兩張圖是一樣的？還有這題要怎麼判斷？

(33.~35.) People in Taiwan never worry about getting hungry at night when there is nothing at home. They can walk to the convenience stores and get anything they I want. In fact, in Taiwan, it is not possible that people fail to find a convenience store because it is part of our life. Convenience stores are working 24/7. In other words, finding a place to sit down and take a rest anytime is a piece of cake. In order to grow business, shopkeepers use some smart ways to have the buyers spend more. First, they put the most popular items at the buyers'eye level to let them see the items easily and often. Second, they drive the buyers to buy something cheap and small without thinking too much or give shoppers a special offer like "Buy One And Get One Free.” Third, they try to have the buyers stay at the convenience stores as long as possible by setting up a seating area. They think the buyers will buy one drink after another once they stay longer. In a study, 73 teenagers answer two of the questions. The pictures below show their interesting answers. Which of the following do you like? The taste of the foods. The service. 146 (63%) 132 (43.8%) The prices of the products. |12 (16.4%) The feelings in the convenience stores. 121 (28.8%) The polite clerks. 16(8.2%) The special offer. 14(19.2%) The way of showing the products. 21 (28.8%) 0 10 20 50 30 40 Which of the following do you like?

率小於逆反應速率 2. A、B 兩種無色氣體混合反應後可產生紅色的C氣 體,其反應式為:3A+B=C+熱量,則下列敘述 何者錯誤? (A)此反應為一可逆反應 (B)當5公升的A氣體與1公升的B氣體在開放的系 統中進行反應,馬上即可達到平衡狀態 (C)正反應為一放熱反應 (D)正反應速率加快時,反應物與生成物的總分子數會 減少 了 3. 2NO2 = N2O4 反應平衡後,下列敘述何者正確? (A)當溫度升高時,氣體顏色變淡深 A (B)當溫度降低時,氣體的總分子數減少 (C)當反應達平衡時,NO的莫耳數恰為NO的兩倍 (D)當反應達平衡時,NO的濃度恰為NO的兩倍 正反應速率=5×10-3草耳 /
