16. Chemical Equilibrium

Consider the reaction A(aq) ⇌ B(aq) in an equilibrium state where KC < 1. The rate of the reaction A(aq) → B(aq) at equilibrium is 59.9 mol/s. What is the rate of the reaction B(aq) → A(aq) at equilibrium?

Which of the following is true about the role of solids and liquids in equilibrium processes?

Consider the following reaction: CO(g) + 2H2(g) ⇌ CH3OH(g). The reaction between CO and H2 is carried out at a specific temperature with initial concentrations of CO = 0.31 M and H2 = 0.55 M. At equilibrium, the concentration of CH3OH is found to be 0.10 M. What is the equilibrium concentration of CO?

For the isomerization reaction butane ↔ isobutane, Kp equals 25 at 500°C. If the initial pressures of butane and isobutane are 10.0 atm and 0.0 atm, respectively, what are the pressures of the two gases at equilibrium?

For the reaction 2NO(g) ⇌ N2(g) + O2(g) at a temperature where Kc = 0.055, the initial concentration of NO is 0.0100 M with no N2 or O2 present. What is the equilibrium concentration of NO?

Which statement best describes the condition of a chemical system at equilibrium?
