Question 1

what is a homogenous reaction

Answer 1

all reactants and products are in the same phase

Question 2

what does Kc stand for

Answer 2

equilibrium constant

Question 3

what does Kp stand for

Answer 3

equilibrium constant of partial pressure

Question 4

what is the only factor that effects equilibrium constant

Answer 4

temperature

Question 5

what are the 2 ways of obtaining a value for the equilibrium constant

Answer 5

experimentation
thermodynamic equations

Question 5

what is the general equation for Kp
wA + xB -> yC + zD

Answer 5

Kc = [C]y [D]z/[A]w [B]x

Question 5

what is a heterogeneous reaction

Answer 5

a reaction which at least one of the reactants/products are in a different phase to the others

Question 6

define partial pressure

Answer 6

the pressure that the gas would exert if it alone occupied the volume of the mixture

Question 7

how do you calculate the partial pressure of an individual gas in a mixture of gases

Answer 7

multiply its mole fraction by the total pressure

Question 8

what is the equation for mole fraction

Answer 8

mole fraction of x = number of moles of x/total number of moles of gas

Question 9

how is Kp effected by temperature

Answer 9

exothermic- Kp decreases with increasing temperature
endothermic- Kp increases with increasing temperature

Question 10

what is the reaction quotient

Answer 10

the mathematical relationship between the concentrations of the components
