Le Chatelier's Principle states that if a chemical system at equilibrium is stressed,.....?
the system will adjust to reduce the stress
.
2SO2(g)+O2(g) ⇌ 2SO3(g) + Heat
Adding SO2(g) will
shift equilibrium right
heat + N2 + O2 <−> 2NO
If O2 is removed, the concentration of N2 will _______.
increase
Changes in pressure will only affect substances that are in the __________ state.
gaseous
N2 (g) + 3 H2 (g) <−> 2 NH3 (g)
If the pressure in the system is increased, which substance will increase in concentration?
NH3
Why is equilibrium called a dynamic state?
The reactions at equilibrium continue to take place once equilibrium is established.
SO2 + O2 <−> SO3
If the concentration of SO2 is increased, the equilibrium of the reaction will shift
right
An equilibrium constant with a large magnitude indicates…
More products at equilibrium
What causes the reaction to go REVERSE
A + B ↔ C + D + energy
Decreasing A
Given the reaction at equilibrium:
2SO2(g) +O2(g) <--> 2SO3(g) + HEAT
Which change will shift the equilibrium to the right?
increasing the pressure
