Static and Dynamic Equilibrium

Question 1

What is a dynamic equilibrium?

Answer 1

The equilibrium has achieved a non-zero rate of forward and reverse reactions being equal in a closed system
(reverse rate = forward rate)

Question 2

What is a static equlibrium?

Answer 2

Where the equilibrium is both the rate of the forward and backward reaction being equal to zero
rate(overall) = 0
- no micro/macro changes
tend to be irreversible reactions

Question 3

Is combustion a static or dynamic equilibrium?

Answer 3

Static, because as it goes to completion, it reaches a rate of zero at the end of the reaction

Question 4

Give an example of a dynamic equilibrium.

Answer 4

Water transferring experiement between two beakers, eventually they will reach the same rate of water being transferred (even if they don’t have the same concentrations)

Question 5

Describe the difference between an open and closed system

Answer 5

An Open system allows energy and mass to be freely travelled throughout the system. In a closed system, the system does not exchange matter, but can allow energy to travel across.

Question 5

Describe the difference between an open and closed system

Answer 5

An Open system allows energy and mass to be freely travelled throughout the system. In a closed system, the system does not exchange matter, but can allow energy to travel across.
