3.4 Flashcards
ideal gas law equation
PV=nRT
P
pressure : the force the gas particles exert on the interior surface of the container through collisions (ATM)
V
volume: the space that the gas occupies (L)
n
number of moles : number of gas particles (mol)
R
ideal gas las constant :0.08206
T
temperature : the avg. kinetic energy of the gas in kelvin (K) (c to K =C+273)
Boyles law (4)
effect of Von P
if all other variables are constant then pv must also be constant
they are inversely proportional
p1xv1=p2xv2
avogadros law
effect of P on n
if all other variables are constant then the equality of pn must also be constant
they are directly proportional
p1/n1=p2/n2
gay lussacs law
effect of p on T
if all other variables are constant then the equality if PT must also be constant
they are directly proportional
p1/t1=p2/t2
Charles law
the effect of v on t
if all other variables are constant then the equality if VT must also be constant
they are directly proportional
v1/t1=v2/t2
daltons law
ptotal= pa+pb+pc
pa=p total x Xa
Xa= moles a / total moles
mole fraction
Xi=ni/ntotal =Pi/ptotal
gas stoichiometry
amount of reactants (v or g)
mole of reactants
moles of product
amount of product
concentration equation (molarity)
c=n/v
STP
T=273K
P=1ATM
V=22.4
