简单化学题,急啊~~,谢谢哪位高手了,最好是不要直接给答案,麻烦写下,应该怎么做?谢谢 Q10 The equilibrium constant K p for the dissociation reaction of the gas A 2
A 2 ( g) ↔ 2 A ( g) was measured as a function of temperature (in K). A graph of lnK p versus 1/T for this reaction gives a straight line with a slope of -1.722x 10 4 and an intercept of 13.83.
Calculate the value of ΔS in J mol -1 K -1 for this reaction.
Q11 The solubility of O 2 in water is 0.601 g/L at an oxygen pressure of 15.38 atm. What is the Henry's law constant k H for oxygen in units of mol L -1 atm -1?
Q12 Calculate Kp for the reaction H2O2 (g) ↔ H2O (g) + 1/2 O2 (g), using the following data:
H2 (g) + O2 (g) ↔ H2O2 (g )Kp= 7.865x 1062 H2 (g) + O2 (g) ↔ 2 H2O (g) Kp= 8.847x 1036
Q13 For a certain reaction at 30°C the value of K is 1.5 x 10-3. At 60°C the value of K is 2.7x10-1.
This means that the reaction is...
Answer
a. more information is needed to find a correct answer.
b. ...exothermic.
c. ...endothermic.
d. always favourable.
e. never favourable.
14 A 3L flask initially contains 1.523 mol of gas A and 0.4449 mol of gas B. Gas A decomposes according to the following equation:
3 A ↔ 2 B + C
The equilibrium concentration of gas C is 0.1 mol/L.
Calculate the value of Kc.
Q15 The reaction H 2 ( g) + I 2 ( g) ↔ 2 HI ( g) has a K p=45.9 at 763 K. A particular equilibrium mixture at that temperature contains gaseous HI at a partial pressure of 3.671 atm and hydrogen gas at a partial pressure of 1.101 atm. What is the partial pressure of I 2 in Pa?
