Equilibrium
T or F?
When a reaction is at equilibrium, there will always be more products than reactants.
False.
K is greater than 1. Are there more products or reactants at equilibrium?
Products
2A(g) + 3B(g) <--> 10C(g) + 4D(g) + 40 kJ
If I added more "A," which way would the equilibrium shift?
Right
The brain has left and right hemispheres. The left hemisphere is thought to be responsible for
a) Creativity
b) Eating
c) Logic
d) Sadness, like how everything in life is just sad
e) Cooking skills
Logic
If Mr. Shin's first name in Korean is Il Chul, what would Mr. Shin's full name in Korean be?
Shin Il Chul
T or F? When a reaction is at equilibrium, K must be greater than 1.
False
K is less than 1. Are there more products or reactants at equilibrium?
Reactants.
2A(g) + 3B(g) <--> 10C(g) + 4D(g) + 40 kJ
If I removed some "B," which way would the equilibrium shift?
Left

a) 3.8 cm
b) 12.5 cm
c) 436.7 meters
d) 2.3 miles
e) Trick question: the moon moves closer to the earth each year
a) 3.8 cm
Mr. Shin wears, on average, how many different types of tie?
1
T or F? When a reaction is at equilibrium, reactants are forming into products while products are forming into products
T
Write the expression for K for the following reaction
4A(g) + 6B(g) <--> C(g) + 3D(g)
Mr. Shin will write the answer on the board.
2A(g) + 3B(g) <--> 10C(g) + 4D(g) + 40 kJ
If I increased the temperature, which molecules would decrease in [ ]?
C and D
Pluto, in what year, was declassified as a planet?
a) 2002
b) 2006
c) 2010
d) 2019
e) 2024
2006
How tall is Mr. Shin
5'11''
When a reaction is at equilibrium and there are equal amounts of products and reactants, the value of K should be
1
Write the expression for K for the following reaction:
4A(g) + 6B(s) <--> 5C(aq) + 7D(l)
Mr. Shin will write the answer on the board
2A(g) + 3B(g) <--> 10C(g) + 4D(g) + 40 kJ
If I decreased the pressure, which molecules would decrease in [ ] in order to reach equilibrium?
A and B
A parrot
a) can fly up to 70 mph when in danger
b) keep its eyes on two different moving targets at once
c) rap Thrift Shop (2012)
d) learn language and speak
e) swim underwater for 5 minutes when in danger
b) keep its eye on two different moving targets at once
Mr. Shin has never watched one of the following tv shows.
a) Spongebob Squarepants
b) Avatar the Last Airbender
c) Gossip Girl
d) The Office
e) Grey's Anatomy
a) Spongebob Squarepants
(Because lets be honest, cartoon network and Kids WB are way better than nickelodeon or Disney Channel)
4A + 4B <--> 4C + 4D
If I increased the pressure from 1atm to 4 atm, how would the equilibrium change? (Would it shift to the left or to the right?)
No change
[A] = 2
[B] = 2
[C] = 8
A + 2B <--> 2C
Solve for K
8
2A(g) + 3B(g) <--> 10C(g) + 4D(g) + 40 kJ
If I were to increase the pressure, there would be an initial increase in [ ] of which molecules?
C and D
What is the name of the scientist who contributed essential programming/research that led to the very first photograph of the black hole (released to the public on April 10th 2019)
