Dynamic Equilibrium - Characterestics

The video tutorial explains reversible reactions using reactants A&B and products C&D, represented as colored balls. It describes how the forward and backward reactions occur, leading to a state of dynamic equilibrium where the rates of both reactions are equal, and concentrations remain constant. The tutorial also includes a graphical representation showing changes in concentrations over time, highlighting the concept of dynamic equilibrium.

What happens to the concentration of reactants A&B at the start of the reaction?

• It decreases.

• It remains constant.

• It fluctuates randomly.

• It increases.

What is the state called when the rate of the forward reaction equals the rate of the backward reaction?

• Reaction balance

• Chemical stasis

• Dynamic equilibrium

• Static equilibrium

At dynamic equilibrium, what happens to the concentrations of reactants and products?

• They remain constant.

• They decrease.

• They increase.

• They fluctuate.

In the graph of a reversible reaction, what does the downward curve represent?

• Increase in reactants

• Decrease in products

• Decrease in reactants

• Increase in products

What does it mean when the curves in the graph become parallel?

• The reaction is at dynamic equilibrium.

• The reaction has stopped.

• The reaction is accelerating.

• The reaction is reversing.
