Answer: Option (4) is the correct answer.
Explanation:
It is known that equilibrium constant is represented as follows for any general reaction.
[tex]A + B \rightarrow C + D[/tex]
K = [tex]\frac{[C][D]}{[A][B]}[/tex]
As equilibrium constant is directly proportional to the concentration of products so more is the value of equilibrium constant more will be the number of products formed.
As a result, more is the time taken by the reaction to reach towards equilibrium. Whereas smaller is the value of equilibrium constant more rapidly it will reach towards the equilibrium.
Thus, we can conclude that cases where K is a very small number will require the LEAST time to arrive at equilibrium.
We cannot tell in which case it will take the least time to arrive at equilibrium since the time to arrive at equilibrium does not depend on K.
What is the equilibrium constant?
The equilibrium constant (K) is a number that expresses the relationship between the amounts of products and reactants present at equilibrium in a reversible chemical reaction at a given temperature.
In which of the following cases will the LEAST time be required to arrive at equilibrium?
- 1. Cannot tell since the time to arrive at equilibrium does not depend on K. True. The time to arrive at the equilibrium depends on the rate constant (k), not on the equilibrium constant (K).
- 2. K is a very large number. False. The time to arrive at equilibrium does not depend on K.
- 3. K is about 1. False. The time to arrive at equilibrium does not depend on K.
- 4. K is a very small number. False. The time to arrive at equilibrium does not depend on K.
- 5. Cannot tell without knowing the value of K. False. The time to arrive at equilibrium does not depend on K.
We cannot tell in which case it will take the least time to arrive at equilibrium since the time to arrive at equilibrium does not depend on K.
