Le Chateliers principle

Question 1

What is Le Chatelier’s Principle?

Answer 1

Le Chatelier’s Principle states that if a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change and restore a new equilibrium.

Question 2

True or False: Le Chatelier’s Principle applies only to gaseous reactions.

Answer 2

False

Question 3

Fill in the blank: According to Le Chatelier’s Principle, increasing the concentration of reactants will shift the equilibrium to the ______.

Answer 3

right

Question 4

What effect does increasing temperature have on an endothermic reaction at equilibrium?

Answer 4

It shifts the equilibrium to the right, favoring the formation of products.

Question 5

In a reaction where the volume decreases, which direction will the equilibrium shift if there are more moles of gas on the reactants side?

Answer 5

To the right, towards the products side.

Question 6

Multiple Choice: Which of the following changes will NOT affect the position of equilibrium? A) Adding a catalyst B) Changing temperature C) Changing pressure

Answer 6

A) Adding a catalyst

Question 7

Short Answer: What happens to the equilibrium position when the pressure is increased in a reaction involving gases?

Answer 7

The equilibrium shifts towards the side with fewer moles of gas.

Question 8

True or False: Decreasing the concentration of products will shift the equilibrium to the left.

Answer 8

True

Question 9

What is the effect of decreasing temperature on an exothermic reaction at equilibrium?

Answer 9

It shifts the equilibrium to the right, favoring the formation of products.

Question 10

Fill in the blank: The principle that describes how a system at equilibrium responds to changes is known as ______.

Answer 10

Le Chatelier’s Principle
