1.
For the reaction shown Kc = 0.5. The table gives concentrations (mol L−1) at one instant. Which option is correct?
For the reaction shown Kc = 0.5. The table gives concentrations (mol L⁻¹) at one instant. Which option is correct?
Q = 31.2, the reaction proceeds not at all (at equilibrium)
Q = 31.2, the reaction proceeds backward
Q = 62.5, the reaction proceeds forward
Q = 1.67, the reaction proceeds not at all (at equilibrium)
2.
For the reaction shown Kc = 4. The table gives concentrations (mol L−1) at one instant. Which option is correct?
For the reaction shown Kc = 4. The table gives concentrations (mol L⁻¹) at one instant. Which option is correct?
Q = 0.08, the reaction proceeds forward
Q = 0.08, the reaction proceeds backward
Q = 0.4, the reaction proceeds forward
Q = 0.08, the reaction proceeds not at all (at equilibrium)
3.
For the reaction shown Kc = 1. The table gives concentrations (mol L−1) at one instant. Which option is correct?
