Pressure, volume change on equilibrium

The video explains how the yield of a gaseous reaction is influenced by changes in container volume, highlighting Boyle's law where pressure is inversely proportional to volume. It discusses how pressure or volume changes occur with variations in the number of gas moles. The total pressure is the sum of individual gas partial pressures. An increase in pressure results in more gas molecules and higher concentration. The number of moles is directly proportional to the partial pressure of gases.

What happens to the yield of a product in a gaseous reaction when the volume of the container changes?

• It remains constant.

• It decreases.

• It changes.

• It doubles.

According to Boyle's law, how is pressure related to volume?

• Exponentially proportional

• Unrelated

• Inversely proportional

• Directly proportional

When does a change in pressure or volume occur in a gaseous reaction?

• When the container is sealed

• When temperature changes

• When the number of moles of gas changes

• When the reaction is complete

What is the total pressure of a reaction mixture equal to?

• The pressure of the largest gas

• The pressure of the smallest gas

• The sum of partial pressures of individual gases

• The average pressure of all gases

How does an increase in pressure affect the concentration of gas molecules?

• It decreases the concentration.

• It has no effect.

• It doubles the concentration.

• It increases the concentration.
