高校化学・熱化学の範囲です。 この問題(写真1枚目)から、このエネルギー図(写真2枚目)を作る考え方がわかりません。 上の図が(2)で使用する図で、下の図が(3)で使用する図になります。 どちらもわかりません。

総合問題 325. 結晶とエネルギー 塩化ナトリウム NaClの結晶を 気体状態のNa原子および CI 原子にするのに必要なエ ネルギーは 624kJ/mol である。 また, 気体状態の Na 原 子を Na + に, CI 原子を CI にイオン化するときの熱量 変化は,それぞれ Na原子のイオン化エネルギー 496 kJ/mol および CI 原子の電子親和力 349kJ/mol に相当 する。 以上のデータから、 右のエネルギー図を描くこと ができる。 一方で気体状態のイオンが多量の水に溶解し たときに発生する熱量は, Na+ では 406kJ/mol, Cl- で は 361 kJ/mol である。 (1) 図中の(ア), (イ) の状態を表す適切な化学式を記して, エネルギー図を完成させよ。 なお, 化学式ではその物質の状態を A13+aq や H2O (気) のように記せ。 (2) 図中のQは何kJ になるか。 (3) Na+aq+Claq の状態をエネルギー図中に記せ。 (4) 塩化ナトリウムが水に溶解する際の溶解熱を求めよ。 また,この変化を熱化学方 程式で表せ。 (11 名古屋大 改) エネルギー Na+(気)+CI-(気) (ア) (イ) Q[kJ] 624kJ
