CH15: CHEM. EQUILIBRIUM

Question 1

⇌

Answer 1

dynamic equilibrium (where processes can go forward and backwards in direction (reversible))

Question 2

K (cursive)

Answer 2

equilibrium constant

Question 3

Large K (cursive) in terms of the L.M.A

Answer 3

high concentration of products at equilibrium

Question 4

Small K (cursive) in terms of the L.M.A

Answer 4

high concentration of rcts at equilibrium

Question 5

Rxn shifts right (⇌)

Answer 5

when an area has a higher concentration of rcts, then the rxn shifts to create more products

Question 6

Rxn shifts left (⇌)

Answer 6

when an area has a higher concentration of products, then the rxn shifts to create more rcts. this process is called reverse rxn

Question 7

fetal HMG vs. adult HMG

Answer 7

f’s K > a’s K cuz f is more efficient at binding O2

Question 8

dynamic equilibrium

Answer 8

the rate of the forward and reverse rxns are equal and the concentration of all chem.s remain constant

Question 9

what is false belief about dynamic equilibrium?

Answer 9

concentration of rcts and concentration of products are equal, but they’re not

Question 10

Law of Mass Action - Definition

Answer 10

mathematical description relating chem. equ. to the concentra. of rcts and products

Question 11

Law of Mass Action - Equa.

Answer 11

K = ([C]^c[D]^d)/([A]^a[B]^b) –> where coef. –> expo.s and the equ. is always products over rcts

Question 12

when the chem. equ. is written backwards, then the K (cursive) is…

Answer 12

inverted

Question 13

K in terms of a backwards chem. equ.

Answer 13

Ksub”backwards” = 1/(Ksub”forwards”)

Question 14

when the chem. equ. is multipled by a factor, then the K (cursive) is…

Answer 14

raised to that factor (meaning the coef. –> expo.s)

Question 15

when the chem. equ. is added tgt, then the K (cursive) is…

Answer 15

Ksub”1” multiplied by Ksub”2”

Question 16

K (cursive) for rxns w/ gasses

Answer 16

Ksub”c” and Ksub”p”

Question 17

Ksub”c”

Answer 17

for equ. involving concentrations in M (molarity)

Question 18

Ksub”p”

Answer 18

for equ. involving gasses in pressure (atm)

Question 19

equ. showing the relationship btwn Ksub”c” and Ksub”p”

Answer 19

Ksub”p” = Ksub”c”(RT)^(delta”n”)

Question 20

exclusions from the K (cursive) expression/equ.

Answer 20

pure liquids (l) and pure solids (s) –> why? their concentration does not change

Question 21

ICE tables

Answer 21

Initial, Change, Equilibrium
