- 1. Multiple Choice
2SO2(g)+O2(g) ⇌ 2SO3(g) + Heat
Adding SO2(g) will
shift equilibrium right
shift equilibrium left
increase rate of reaction
have no change
- 2. Multiple Choice
2SO2(g)+O2(g) ⇌ 2SO3(g) + Heat
Increasing the temperature will...
shift equilibrium right
shift equilibrium left
increase pressure
have no change
- 3. Multiple Choice
2SO2(g) + O2(g) ⇌ 2SO3(g) + Heat
Removing O2(g) will
shift equilibrium right
shift equilibrium left
increase pressure
have no change
- 4. Multiple Choice
2SO2(g)+O2(g) ⇌ 2SO3(g) + Heat
Adding SO3(g) will
shift equilibrium right
shift equilibrium left
increase K
have no change
- 5. Multiple Choice
2CrO42- + 2H+ → Cr2O72- + H2O
If the system is at equilibrium and initially has some of both the reactants and the products in the solution, what will happen when H+ ions are added to the system?
(Check all that apply!)
The forward reaction rate will increase temporarily
The reverse reaction rate will increase temporarily
The equilibrium will shift left making the system look more orange
The equilibrium will shift right making the system look more yellow
Nothing will happen because the system was already at equilibrium
- 6. Multiple Choice
N2O4 + heat ↔ 2 NO2
If the system is at equilibrium and initially has some of both the reactants and the products in the solution, how and why can we go something to the heat to get more products to be made?
(Check all that apply!)
Add heat
Remove heat
Heat is a reactant so adding heat will increase the rate of the forward reaction.
Heat is a reactant so removing heat will increase the rate of the forward reaction.
Increasing the forward reaction will make more of the products.
