- 3. Multiple ChoiceIn the equation Kc = Kp(RT)Δn , the Δn meansThe sum of all the moles.moles of products - moles of reactantsmoles of reactants - moles of productreaction order
- 4. Multiple ChoiceN2O4(g) ↔ 2 NO2(g)
What is the concentration equilibrium constant expression?Kc = [NO2]2/[N2O4]Kc = [N2O4]/[NO2]2Kc = [N2O4]2/[NO2]Kc = [NO2]/[N2O4]2 - 5. Multiple ChoiceN2O4(g) ↔ 2 NO2(g)
What is the equilibrium constant expression?Kp = (PNO2)2/ (PN2O4)Kp = (PN2O4) / (PNO2)2Kp = (PN2O4)2 / (PNO2)Kp = (PNO2) / (PN2O4)2 - 6. Multiple ChoiceFor the equilibrium
2SO3(g) ↔ 2SO2(g) + O2(g)
Kc = 4.08x10-3 at 1000K
What is Kp?3.45 x 1052.990.3353.4 x 10-5 - 7. Multiple ChoiceWhat is the equilibrium-constant expression for
CO2(g) + H2(g) ↔ CO(g) + H2O(l)Kc= [CO][H2O] / [CO2][H2]Kc= [CO2][H2] / [CO]Kc= [CO2][H2] / [CO][H2O]Kc= [CO] / [CO2][H2] - 8. Multiple ChoiceFind the Kc for
2NOBr(g) + Cl2(g) ↔ 2NO(g) + 2BrCl(g)
if
2NOBr(g) ↔ 2NO(g) + Br2(g)
