Introduction to Chemical Equilibrium – Human Respiration

The video tutorial explains the role of chemical reactions in biological processes, focusing on breathing. It describes how oxygen and hemoglobin react to form oxyhemoglobin in a forward reaction, which then decomposes back into reactants in a backward reaction, making it a reversible process. The concept of equilibrium in these reactions is also discussed, highlighting the balance between reactants and products.

What are the reactants involved in the formation of oxyhemoglobin?

• Oxygen and hemoglobin

• Carbon dioxide and hemoglobin

• Oxygen and carbon dioxide

• Water and hemoglobin

What happens to oxyhemoglobin in the backward reaction?

• It forms carbon monoxide

• It forms water and carbon dioxide

• It decomposes into hemoglobin and oxygen

• It remains stable

Why is the breathing process considered a reversible reaction?

• Because it only involves a forward reaction

• Because it involves both forward and backward reactions

• Because it only involves a backward reaction

• Because it is an irreversible process

What symbol is used to represent equilibrium in reversible reactions?

• Double-headed arrow

• Single-headed arrow

• Equal sign

• Plus sign

What does the double-headed arrow indicate in the context of reversible reactions?

• The reaction is only forward

• The reaction can proceed in both directions

• The reaction is only backward

• The reaction is irreversible
