2番の問題なんですけど、計算に生成した水の圧力を含めて考えないんですか?

BAR 新潟大 226 混合気体と飽和蒸気圧 次の文を読み、あとの各問いに答えよ。 気体は理想気体とし、水には溶けないものと する。また,液体の水の体積は無視でき, 127℃の水の飽和蒸気圧は 2.5×10Pa とす |気体定数 8.31×10Pa・L/(mol・K) 1.0mol の水素 H2 と2.0molの酸素 O2 の混合気体を体積が変化するピストン容器 に入れ,気体の温度を27℃ 全圧を1.0×105Paにした。次に, ピストン容器の体積 る。 を一定に保ったまま,容器内の気体に点火して完全燃焼させた後,気体の温度が127℃ になるまで放置した。 最後に、 (ウ) (1) 下線部 (ア)について、 容器内の水素の分圧 [Pa] を求めよ。 (2) 下線部(イ)について, 容器内の酸素の分圧〔Pa〕 を求めよ。 (3) 下線部(ウ)の操作による体積と全圧の変化を表すグラフを. 次の(a)~(d)から選べ。 点 Aにおいて, 水の状態が変化し始め、そのときの体積を VA とする。 (a) (b) (c) 全圧↑ 0 B A 0 全圧↑ 容器の体積を減少させた。 温度を127℃に保ったまま、 B 186 A 全圧↑ B (d) 全圧 B• ERUAR [ass A VA 体積 0 VA 体積00 VA 体積 VA 体積 (4)(3)で選んだ図の点Aから点Bへの過程では水はどのような状態変化をするか。 (5) (3)で選んだ図の体積 VA [L] を求めよ。
