For an exothermic reaction, raising the temperature shifts the equilibrium towards the reactants.
True
Arrange the following stresses in the order they affect equilibrium according to Le Châtelier's Principle:
1️⃣ Increase in Reactants
2️⃣ Increase in Products
3️⃣ Increase in Temperature (Endothermic)
4️⃣ Increase in Temperature (Exothermic)
5️⃣ Increase in Pressure
Temperature changes affect equilibrium based on whether a reaction is exothermic or endothermic.
Increasing pressure in a system at equilibrium shifts it towards the side with fewer moles of gas.
True
Temperature changes affect equilibrium differently depending on whether the reaction is exothermic or endothermic.
True
How does a temperature change affect equilibrium in an exothermic reaction?
Depends on temperature change
Arrange the steps in how concentration changes affect equilibrium according to Le Châtelier's Principle.
1️⃣ Increase reactants
2️⃣ Equilibrium shifts right
3️⃣ Produce more products
Decreasing the temperature in an exothermic reaction favors the formation of products.
True
How does increasing pressure affect the equilibrium in a reaction with gases?
Shifts towards fewer moles
Adding an inert gas to a system at equilibrium increases the total pressure but does not change the partial pressures of reactants or products.
What does Le Châtelier's Principle state about a system at equilibrium when stressed?
It shifts to counteract the stress
If you add more reactants in the reaction H₂ + I₂ ⇌ 2HI, the equilibrium will shift to the right
In the reaction N₂(g) + 3H₂(g) ⇌ 2NH₃(g), adding more N₂ will shift the equilibrium to the right
What happens to equilibrium if the concentration of reactants is increased?
It shifts to the right
What happens to equilibrium in an endothermic reaction if the temperature is increased?
It shifts to the right
Le Châtelier's Principle states that if a stress is applied to a system at equilibrium, the system will shift to counteract the stress.
When a system at equilibrium experiences a concentration change, the equilibrium shifts towards the side that minimizes the stress
In the reaction H₂ + I₂ ⇌ 2HI, what happens to the equilibrium if more H₂ is added?
Shifts to the right
What happens to the equilibrium in an exothermic reaction if the temperature increases?
Shifts to the left
For the exothermic reaction N₂(g) + 3H₂(g) ⇌ 2NH₃(g) + Heat, what happens to the equilibrium if the temperature is lowered?
Shifts to the right
What is an inert gas and how does it affect equilibrium?
No reaction, unaffected
In the endothermic reaction N₂(g) + 3H₂(g) + heat ⇌ 2NH₃(g), what happens to the equilibrium if the temperature is increased?
Shifts to the right
Decreasing reactants in an equilibrium system shifts the equilibrium to the left.
True
Increasing pressure in a system at equilibrium shifts it towards the side with fewer moles of gas.
True
In an exothermic reaction, increasing the temperature shifts the equilibrium to the left.
True
What happens to equilibrium if the volume of a system at equilibrium is increased?
It shifts towards more moles of gas
What is Le Châtelier's Principle?
Counteract stress and restore equilibrium
A pressure change in an equilibrium system shifts towards the side with fewer moles of gas.
True
In the reaction N₂(g) + 3H₂(g) ⇌ 2NH₃(g), what happens to the equilibrium if more N₂ is added?
Shifts to the right
In the endothermic reaction \text{Heat} + CaCO_3(s) \rightleftharpoons CaO(s) + CO_2(g)</latex>, increasing the temperature shifts the equilibrium to the right
Decreasing the volume of a system at equilibrium will shift the equilibrium towards fewer moles of gas.
True
In the reaction H₂(g) + I₂(g) ⇌ 2HI(g), adding more H₂ shifts the equilibrium to the right.
