1Which of the following conditions must be met for a chemical system to be at equilibrium?
2In the escalator analogy for dynamic equilibrium, what represents the 'rate' of the processes?
3For the reaction I2(g) + 3Cl2(g) ℌ 2ICl3(g), what is the correct mathematical expression for the equilibrium constant (Kc)?
4If the equilibrium constant (Kc) for a reaction is 0.00045, what does this tell you about the equilibrium position?
5A reaction system currently has a reaction quotient (Qc) of 12.5, while its known equilibrium constant (Kc) is 2.1. Which of the following describes the behavior of the system?
6The reaction 2SO2 + O2 ℌ 2SO3 has a Kc of 1000. If the reaction is reversed to 2SO3 ℌ 2SO2 + O2, what is the new Kc value?
7Given the reaction 2N2O(g) ℌ 2N2(g) + O2(g) with Kc = 7.3 x 10^34, what is the Kc for the reaction N2(g) + 0.5O2(g) ℌ N2O(g)?
8Identify the true statements regarding reversible reactions and equilibrium.
9Calculate Kc for the reaction CO2(g) + H2O(l) ℌ H2CO3(aq) if the equilibrium concentrations are: [H2CO3] = 2.00 M, [CO2] = 34.00 M, and [H2O] = 34.00 M. (Round to 5 decimal places)
10If you multiply the coefficients of a balanced chemical equation by 3, how does the new equilibrium constant (Kc') relate to the original (Kc)?
