Question 2 Given the reaction, 2 NO(g) + O2(g) ⇌ 2 NO2(g), forwhich the enthalpy of reaction is ‑118.9 kJ. Which one of thefollowing will cause an increase in the equilibrium concentrationof NO in a closed reaction chamber? A. adding some more O2(g)through an injection nozzle B. adding a catalyst C. increasing thepressure of the system while temperature is kept constant D.increasing the temperature of the system .

Question 3 Consider the following system, which is atequilibrium, 3 C(s) + 3 H2(g) ⇌ CH4(g) + C2H2(g) The result ofremoving some C(s) from the system will be: A. more C(s) isproduced B. no further change occurs C. Kc increases D. more CH4(g)and C2H2(g) are produced to restore the equilibrium .

Question 4 A student is preparing a study of the reaction, 2CO2(g) ⇌ 2 CO(g) + O2(g), for which Kc = 26.2 at 827 oC. What isthe value of Kp at that same temperature? A. 3.86 x 10-1 B. 2.90 x10-1 C. 2.36 x 10+3 D. 2.40 x 10+5

Can somone explain how you came up with the answers too.Thanks.
