Question 1

ksp=

Answer 1

[cat]^x [anion]^y

Question 2

rate of BaF2 (s) to Ba2+ and 2F-

Answer 2

ksp=(x)(2x)^2= 4x^3

Question 3

what does x represent?

Answer 3

molar solubility

Question 4

with increasing temp, Ksp

Answer 4

increases (for solid) and decreases for gas

Question 5

complex ion is made of

Answer 5

metal and lewis base

Question 6

collision theory =

Answer 6

rate= Zf

Question 7

arrhenius equation

Answer 7

k= Ae^ (-Ea/RT)

Question 8

As Ea decreases or T increases,

Answer 8

K increases

Question 9

definition of rate for aA–> cC

Answer 9

-[A]/a(change in time) = +[C]/c(change in time)

Question 10

rate law

Answer 10

rate= k [A]^x [B]^y and x and y are experimentally determined only (reactants only)

Question 11

radioactive decay

Answer 11

[A]f= [A]i e^(-kt)

first order reaction

Answer 12

t (1/2)= 0.693/k

Question 13

zeroth order

Answer 13

rate= k

unit (M/s)

Question 14

first order

Answer 14

rate= k[A]

unit 1/s

Question 15

second order

Answer 15

rate= k[A]^2 (example)

unit 1/Ms

Question 16

third order

Answer 16

unit 1/(M^2) 1/s

Question 17

equilibrium constant keq=

Answer 17

keq= products/reactants (with exponents being coefficients)

l and solids not included

Question 18

reaction quotient

Answer 18

same thing but not at equilibrium

Question 24

kp to kc

Answer 24

Kp= Kc (RT)^delta n

Question 25

bicarbonate buffer equation

Answer 25

CO2 + H2O— H2CO3—–H+ + HCO3-

Question 26

kinetic product

Answer 26

fast, at low T and less stable
