Question

What does it mean for a system to be in dynamic equilibrium? (2 points)
Select one:
a. The rate of the forward reaction equals the rate of the backward reaction.
b. The concentration of products decreases.
c. The overall rate of the reaction slows down.
d. The temperature of the system is stable.

Answer 1

Answer:

A

Explanation:

A dynamic equilibrium is a chemical equilibrium between a forward reaction and the reverse reaction where the rate of the reactions are equal.

Answer 2

The rate of the forward reaction equals the rate of the backward reaction.

For a system to be in dynamic equilibrium, the forces should be balanced.

What is dynamic equilibrium?

According to chemistry, Dynamic equilibrium is all about the equal rate of change in reactants and products, i.e., there will be a steady state. Also in Physics, if though the number of the composition of mixtures happens and that does not change with time, i.e., it is equilibrium constant. For example, when the car moving on the road, there will be some friction. The forward force of the car happened due to friction but no other force has changed at car's constant speed. When the net force will be same then it is known to be dynamic equilibrium.

Equilibrium constants can be determined as rate constants through reversible reaction, i.e., the rate of the forward reaction equals to the rate of the backward reaction.

Thus, option A is correct.
