Test: Applications of Equilibrium Constants (10 July) - Question 1

What does the equilibrium constant (K) represent for a chemical reaction?

Detailed Solution for Test: Applications of Equilibrium Constants (10 July) - Question 1
The equilibrium constant (K) represents the ratio of product concentration to reactant concentration for a chemical reaction at equilibrium.

Test: Applications of Equilibrium Constants (10 July) - Question 3

What is the relationship between the equilibrium constant Kc and the Gibbs free energy (ΔG) of a reaction?

Detailed Solution for Test: Applications of Equilibrium Constants (10 July) - Question 3

When ΔG is greater than 0 and Qc is greater than Kc, it indicates a spontaneous reaction in the forward direction.

Test: Applications of Equilibrium Constants (10 July) - Question 4
What is the relationship between the forward and backward reaction rate constants at equilibrium?
Detailed Solution for Test: Applications of Equilibrium Constants (10 July) - Question 4
The forward and backward reaction rate constants are constant at a given temperature, leading to the establishment of the equilibrium constant.
Test: Applications of Equilibrium Constants (10 July) - Question 5
What happens to the equilibrium constant (K) of a reaction if the stoichiometry of the equilibrium reaction changes?
Detailed Solution for Test: Applications of Equilibrium Constants (10 July) - Question 5
If the stoichiometry of the equilibrium reaction changes, the equilibrium constant K remains the same as it is specific to the balanced equation at a given temperature.
Test: Applications of Equilibrium Constants (10 July) - Question 6
What happens to the equilibrium constant (K) when a catalyst is added to a reaction?
Detailed Solution for Test: Applications of Equilibrium Constants (10 July) - Question 6
The presence of a catalyst does not change the value of the equilibrium constant (K); it only affects the rate of the forward and backward reactions.
Test: Applications of Equilibrium Constants (10 July) - Question 7
How does the equilibrium constant (K) change with temperature for the same reversible reaction?
Detailed Solution for Test: Applications of Equilibrium Constants (10 July) - Question 7
The equilibrium constant (K) can have varying values at different temperatures for the same reversible reaction. It increases with increasing temperature.
Test: Applications of Equilibrium Constants (10 July) - Question 8

In the case of stepwise multiple equilibria leading to final products, how is the net equilibrium constant (K) determined?

Detailed Solution for Test: Applications of Equilibrium Constants (10 July) - Question 8

In the case of stepwise multiple equilibria leading to final products, the net equilibrium constant (K) is determined by taking the product of each stepwise equilibrium constant (K1 * K2 * K3).

Test: Applications of Equilibrium Constants (10 July) - Question 9

What unit is typically used for Kc, the equilibrium constant measured in terms of concentration?

Detailed Solution for Test: Applications of Equilibrium Constants (10 July) - Question 9

Kc is typically measured in moles per liter (mol/L) as it represents the concentration of products and reactants.

Test: Applications of Equilibrium Constants (10 July) - Question 10

How is the direction of a reaction determined using the equilibrium constant (K) and the reaction quotient (Q)?

Detailed Solution for Test: Applications of Equilibrium Constants (10 July) - Question 10

The correct answer is:

a) By comparing Q to K, where Q > K indicates a backward reaction, and Q < K indicates a forward reaction.

Explanation:

  • The reaction quotient Q is calculated using the concentrations of the reactants and products at any point during the reaction.
  • The equilibrium constant K is the value of Q when the reaction is at equilibrium.
  • If Q<K, the reaction will proceed in the forward direction to reach equilibrium (products are favored).
  • If Q>K, the reaction will proceed in the reverse direction to reach equilibrium (reactants are favored).
  • If Q=K, the reaction is at equilibrium, and there is no net change in the concentration of reactants and products.
