gas equilibria and Kp Flashcards
1
Q
how can you calculate the total pressure of gas mixture
A
by adding all the partial pressures of the individual gases
2
Q
what is a mole fraction
A
the proportion of a gas mixture that is made up of a particular gas
3
Q
what is the formula for mole fraction of a gas in a mixture
A
number of moles of gas/total number of moles of gas in the mixture
4
Q
what is the formula for working out partial pressure of a gas
A
mole fraction of gas X total pressure of the mixture
5
Q
what is the definition of Kp
A
the equilibrium constant for a reversible reaction where all the reactants and products are gases
6
Q
how is the formula different for working out Kp from Kc
A
you use partial pressures instead of concentrations
7
Q
what affects the value of Kp
A
temperature
