2) For the reactionA(g)⇌2B(g), a reaction vessel initiallycontains only A at a pressure of PA=1.28 atm . At equilibrium, PA=0.17 atm Calculate the value of Kp. (Assume no changes in volumeor temperature.)
3) Consider the reaction: 2NO(g)+Br2(g)⇌2NOBr(g) Kp=28.4 at 298K
In a reaction mixture at equilibrium, the partial pressure of NO is102 torr and that of Br2 is 160torr .What is the partial pressureof NOBr in this mixture?
4) The system described by the reactionCO(g)+Cl2(g)⇌COCl2(g)
is at equilibrium at a given temperature when PCO= 0.28 atm , PCl2=0.10 atm , and PCOCl2= 0.61 atm . An additional pressure of Cl2(g)=0.40 atm is addedFind the pressure of CO when the system returns toequilibrium.
5)At 650 K, the reaction MgCO3(s)⇌MgO(s)+CO2(g) has Kp=0.026. A12.5 L container at 650 K has 1.0 g of MgO(s) and CO2 at P = 0.0260atm. The container is then compressed to a volume of 0.500 L Findthe mass of MgCO3 that is formed.
6) Consider the following reaction:
SO2Cl2(g)⇌SO2(g)+Cl2(g)
Kc=2.99×10−7 at 227∘C
If a reaction mixture initially contains 0.168 M SO2Cl2, what isthe equilibrium concentration of Cl2 at 227 ∘C?
