[مهندس صنآعي]

السلام عليكم

اتمنى اللي يعرف الاجابة يساعدني الله يجزاكم خير مع العلم ان الاختيارات تحتمل اكثر من اجابة صحيحة يعني عادي اجابتين على كلام الدكتور


السؤال الاول

Consider the equilibrium

2NaHSO3(s) <==> Na2SO3(s) + H2O(g) + SO2(g

How will the production of SO2 be increased?

A. Increasing the volume of the reaction vessel
B. Removing H2O to the reaction vessel
C. Removing Na2SO3 from the reaction vessel (it is not completely removed
D. Adding NaHSO3 to the reaction vessel


السؤال الثاني

Consider the equilibrium 2NO (g) + Cl2(g) <==> 2NOCl(g) for which delat_Ho = -77.07 kJ.

Which of the following changes will increase the amount of Cl2 ?

A. Removing NO(g
B. Removing NOCl(g
C. Raising the temperature
D. Decreasing the volume of the container


السؤال الثالث

At 2000 oC, the decomposition of CO2,
2CO2(g) <==> 2CO(g) + O2(g)

has Kc = 4.14 × 10-7. If a 9.00 L container holding 1.00 × 10-2 mol of CO2 is heated to 2000 oC, what will be the partial pressure of CO (in atmospheres) at equilibrium? Enter your answer in scientific notation


السؤال الرابع

What is the boiling temperature of water under under a pressure of 884 torr?
The heat of vaporization of water is ΔHfus = 335.0 J g-1
