問5(1)について Kp=PCO2=1.0×10^5Paとなるのは何故ですか?

図1に示すような質量が無視できるフタが付いた容器がある。 このフタはなめ らかに動き、フタの移動により容器の内容積は0L~10.0Lの範囲で変化する。ま た. フタの位置を固定して内容積を一定に保つこともできる。 このフタ付き容器を 用いて (式1) の反応に関する操作1 ~ 操作 4 をおこなった。 下の設問 (1)~(4) に答え よ。 大気圧は常に100×10Pa であり、追加したアルゴンは化学反応を起こすこと はなく、アルゴンの固体への吸着も起こらなかった。また,固体試料の体積は無視 できるものとし、容器内の気体については理想気体の法則が使えるものとする。 問5 10.0 L ■固体試料 mooooooo 熱源 図 1 フタ - 14- 17.50g 5,80( nitog @ m 100 操作1:フタ付き容器に固体試料として7.50gの純粋な炭酸カルシウムを入れた後, 内容積が5.80 L になるようにフタを固定した。 排気し容器内の気体をすべて取 り除いた後,温度を上げると,やがて炭酸カルシウムの分解が起こり始めた。 温度が887℃になったところで, その温度を保ち十分な時間を経過させた。 操作2:操作1に続き, フタを固定したまま, 容器内にアルゴンを0.0350 mol 封入 した。温度を887℃に保って十分な時間を経過させた。 操作3:操作2に続き, フタを固定したまま、質量数13の炭素原子13C (相対質量 13.0) だけからなる二酸化炭素 13 CO2 を 0.0500mol 封入した。 温度を887℃に 保って十分な時間を経過させた。 操作4:操作3に続き、フタの固定を外し,温度を887℃に保って十分な時間を経 過させた

When I was invited to an 次の英文を3分15秒で読んで, 1. の問いに答えなさい。 American woman's house for Christmas, her mother said to me, "We usually don't have a regular breakfast. Will you need breakfast tomorrow?" Out of reserve, I was not able to say "Yes, I will," because (1)that would require her to prepare breakfast for me 5 alone. I had no choice but to say, "No, thank you. (2)Her mother took me at my word, and assumed that I was also in the habit of skipping breakfast. When I was back at the university after the holidays, I (3)brought up the subject with a few Americans. 4)"If you had been in my place, and had needed breakfast, what would you have said?" One person said, "Your friend's mother was being frank, so I'd 00.00% 10 have said frankly, 'If you could prepare a little breakfast, I'm sure I'd enjoy it. (5) Otherwise, I'll eat out." Another person said, "That's not so polite. I'd have asked her politely, 'If you could prepare breakfast for me, I'd appreciate it." They asked me why I had been reluctant to give a frank opinion. I explained the Japanese cultural viewpoint. In Japan, immediately accepting an 15 offer of a meal is regarded as impudent; such an invitation is supposed to be declined at least once. But the host realizes that the guest has declined out of reserve, and makes it a rule to ask a second time. A Japanese guest never insists on being served a meal. The host understands the situation and the feelings of the guest and reacts appropriately. (7) "That idea has no chance at all of working here," one American said with total frankness. She continued, "Unless you're frank here, you'll go hungry all the time."
