Equilibrium Reactions and Conditions

The video tutorial discusses a question from the ACS exam about equilibrium in a reversible reaction involving carbon monoxide and hydrogen gases. It explains how changes in pressure and temperature affect the equilibrium state, using Le Chatelier's principle. The tutorial concludes that lowering pressure favors the reactant side, resulting in no methanol production, and confirms the correct answer choice.

What is the main focus of the equilibrium question discussed in the video?

• The reversible reaction of carbon monoxide and hydrogen gases.

• It shifts the reaction to the left.

What is the effect of increasing temperature on the equilibrium?

• It causes the reaction to stop.

• It favors the formation of products.

• It favors the formation of reactants.

• It has no effect on the equilibrium.

What is the result of decreasing the concentration of the product?

• No methanol is formed.

• More product is formed.

• The reaction stops.

• The reaction shifts to the right.

What happens to the reaction when both temperature and pressure are increased?

• The reaction shifts to the right.

• The reaction shifts to the left.

• The reaction stops.

• The reaction remains unchanged.

Which of the following is true about the reaction at high pressure?

• It favors the product side.
