Rules in the School Library Grammar Focus Time and Place, Inversion We use phrases with prepositions and adverbs when we describe time and place. They are usually placed at the end of a clause or sentence. However, some emphatic expressions should be placed at the beginning of aclause or sentence and need to have an unusual structure, called inversion. Choose a phrase from the box below to complete each of the following sentences. Use a capital letter to begin the first word of each sentence. 1. The blueprints for the new buildingare on hold ( 2. A radical change in the formula fora new drug will take place ( 3. The scientific program has aired continuously ( ) did scientists decide that air, earth and fire were not really elements at all. 5.

169(2)解説の下から3行目で、3.0<4.0 となるところまでは分かりましたが、そのあとの考え方がわかりません。教えてください。

*169. エステル生成量 (1)酢酸 CH:COOH とエタノール CH:OH を 3.0mol ずつ混ぜ,少量の濃硫酸の存在下で 一定温度に保ったところ,酢酸エチル CHCOOC2H5 と水が 2.0mol ずつ生じたとこ ろで平衡に達した。この反応の平衡定数を求めよ。 (2) (1)の平衡状態にある溶液にさらに酢酸1.0mol と酢酸エチル1.0mol を加えると, 平 衡はどちらに移動するか。 Daaol--Hq ( ており, K。は濃度平衡 主数ともよばれる。 Kcはcを省略してKと 表されることもあり,本 書でもKを使用する。 169: (1) 4.0 (2)酢酸エチル生成の方向 (反応前) (変化量) (平衡時) 溶液の体積をVL] とすると,各物質のモル濃度は, CHCOOH + CaH;OH → CH.COOC2H5 + H:0 3.0 -2.0 1.0 3.0 -2.0 1.0 0 +2.0 2.0 0 (mol) +2.0 (mol) 2.0(mol) 1.0 [CH.COOH]=[CH:OH]= [mol/L] 人 [CH.COOCHs]=[H.0]= 2.0 [mol/L] V 2.0 [CH.COOCHs][H0] [mol/L]× 2.0 -[mol/L] K= V V TCH.COOH][CHOH] 1.0 V -=4.0 1.0 [mol/L]×- -[mol/L] 2)酢酸の物質量は,1.0mol+1.0mol=2.0mol 昨酸エチルの物質量は、2.0mol+1.0mol=3.0mol 谷液の体積をV'[L] として、これらの値を平衡定数の式に代入して 8.0s代 -リ= Va- Vb みると, 平衡 状態 Ca(OH) -Imol/L]× 2.0 [mol/L] 3.0 -[mol/L] ICH.COOCH5][H:0] 0 時間 K'= V [CH.COOH][CHsOH] 1.0 [mol/L]× 2.0 V =3.0<4.0 1Kは, も温度が 一定である エ (1)で求めたKの値 K'はKより小さいから, 4.0になるまで分子の物質が増え, 分母の 物質が減る”。すなわち, 平衡は右に移動し, 酢酸エチルの量が増す。 全) O (1) NeO』の分圧: 4.3×10*Pa, NO2 の分圧: 5.7×10*Pa (2) 7.6×10*Pa ヨ分子と分母で,各物質 の単位 mol/L の次数が 司じになるので、Kには (1) 最初のNeO4をn [mol] とすると, 40%の N:04が解離するので, 反 応したN.O,は0 40m0
