1º ¿Cómo se produce una reacción química?

Summary

The transcript explains the concept of chemical reactions, describing how molecules of reactive substances collide under certain conditions to trigger a reaction. It touches on the reverse reaction where the products of the initial reaction collide, reaching chemical equilibrium. The injection of new reactants disturbs this equilibrium, resulting in the formation of new product molecules until a new balance is reached. The process illustrates how chemical systems stabilize and adjust based on changes in reactant and product concentrations.

Takeaways

• 😀 A chemical reaction is triggered by the collision of molecules from two reactive substances.
• 😀 The reaction occurs under specific conditions where molecules of the reaction products collide with each other.
• 😀 The reverse reaction can take place when molecules of the products collide.
• 😀 Chemical equilibrium is reached when both the forward and reverse processes stabilize.
• 😀 The injection of new reactants disrupts the chemical equilibrium.
• 😀 New molecules of the product are formed when the equilibrium is disrupted.
• 😀 A new chemical equilibrium is reached after the formation of new molecules.
• 😀 Chemical reactions depend on the interaction between molecules and the conditions present.
• 😀 Chemical equilibrium is a dynamic state where the rates of forward and reverse reactions are equal.
• 😀 The process of reaching equilibrium can be influenced by external factors like the addition of reactants.

Q & A

What is triggered by the collision of two molecules in a chemical reaction?

A chemical reaction is triggered when two reactive molecules collide under specific conditions.

What happens when the molecules of the products of a chemical reaction collide?

When the molecules of the products collide, the reverse reaction occurs.

What is chemical equilibrium?

Chemical equilibrium is reached when both the forward and reverse processes in a reaction stabilize and occur at the same rate.

How does the injection of new reactants affect chemical equilibrium?

The injection of new reactants disrupts the equilibrium, leading to the formation of new product molecules until a new equilibrium is reached.

What happens when a chemical equilibrium is disrupted?

When a chemical equilibrium is disrupted, the system adjusts by forming more products or reactants until a new equilibrium is established.

What role do reactants play in chemical reactions?

Reactants are the molecules that collide to start a chemical reaction, leading to the formation of products.

Can a reaction reach multiple equilibria over time?

Yes, a reaction can reach multiple equilibria, especially if new reactants are introduced or the conditions of the reaction change.

How does the system respond to the addition of new reactants in a chemical reaction?

The system responds by adjusting the concentrations of products and reactants to form a new equilibrium state.

What does it mean for a reaction to be in equilibrium?

A reaction is in equilibrium when the rates of the forward and reverse reactions are equal, meaning the concentrations of products and reactants remain constant over time.

Is it possible for a chemical reaction to reach an equilibrium without external influence?

Yes, a chemical reaction can reach equilibrium naturally under stable conditions without external interference.
