Question

w ten species is the catalyst? 6. A mixture with [N:04) - 0.90 and [NO:] = 0.134 at 25°C is at equilibrium as follows: N:04(g) = 2 NOxg) What is the equilibrium constant, Ke, for the reaction? 7. Consider the reaction: C(s) + CO (g) = 2 CO(g), Ke=0.113 at 25°C An equilibrium mixture at 25°C was found to have a CO, concentration of 0.200 M. What is the CO concentration? 8. If Kc - 35 x 10 at 500 K for the reaction: 2 SO2(g) + O2(g) 250 () What is Kp at 500 K for the reaction? 9. The equilibrium constant for the reaction: H2(g) + 12(g) 2 HI(g) is 57 at 425 C. A reaction vessel at 425 C was found to contain 0.150 MH2.0.150 M 12 and 0.50 MHI: a) Tell whether the mixture is at equilibrium or not; and, b) If the mixture is not at equilibrium, tell which direction the reaction will shift to reach equilibrium
