Question

The system is said to be in dynamic equilibrium when:

Select one:

a. there is no longer any net change in the concentrations of products or reactants.

b. the forward and reverse reactions come to a halt.

c. None of these

d. the sum of the concentrations of the reactants is equal to the sum of the concentrations of the products.

e. you have let the reaction proceed for approximately 30 minutes and can assume there will be no more changes.

Answer 1

a) there is no longer any net change in the concentration of products and reactants

Step-by-step explanation:

There is dynamic equilibrium when in a reversivble reaction stop changing your reagents / product ratio; but the substances move at an equal rate; System properties do not change over time.

The system is in dynamic equlibrium if it has all three types of equilibrium:

• mechanic equilibrium: if there is no net force applied to the system
• thermal equilibrium: constant temperature.
• material equilibrium: the composition on the system does not change.
