RULES / THINGS TO REMEMBER

Question 1

what does a larger value of Kc suggest

Answer 1

equilibrium is further to the right

Question 2

what does a smaller value of Kc suggest

Answer 2

equilibrium is further to the left

Question 3

Kc equation

Answer 3

Kc= [product]^mole x [product]^mole / [reactant]^mole x [reactant]^mole

Question 4

what is Kp + Kc affected by

Answer 4

ONLY temp

Question 5

total pressure =

Answer 5

sum of all partial pressures

Question 6

partial pressure =

Answer 6

mole fraction of gas X total pressure

Question 7

mole fraction =

Answer 7

number of moles of gas X total number of moles of gas in a mixture

Question 8

Kp equation

Answer 8

Kp= p(prod)^mol x p(prod)^mol / p(react)^mol x p(react)^mol

Question 9

what state is ONLY included in Kp calculations

Answer 9

ONLY include GAS in the equation

Question 10

pH=

Answer 10

-log([H+]

Question 11

[H+]=

Answer 11

10^-pH

Question 12

Kw equation

Answer 12

Kw= [H+] [OH-]

Question 13

Ka =

Answer 13

Ka= [H+] [A-] / [HA]
.:. Ka= [H+]^2 / [HA]

OR

Ka= 10^-pKa
