Equations Flashcards
partial pressure
=mole fraction x total pressure
mole fraction
= no. of moles of gas A
total no. of gaseous moles
moles
=mass
Mr
concentartion
= moles
volume
pressure x volume
= 8.314 x moles x temperature
volume
= moles x 24
no. of particles
= moles X 6.02 X 10^23
Heat Energy (Q)
=mass x water constant x change in temperature
enthalpy
= heat energy (Q)
moles of reactant
rate
rate constant k x [concentration of A]^order [concentrationB]^order
rate constant
= ln2
half life
Kc
=[concentration of products]^(no. of moles)
[concentration of reactants]^(no. of moles)
Kp
=(Pressure of products)^moles
(Pressure of reactants)^moles
Ka
=(cation)(H+)
(overall)
cell potential
=positive electrode - negative electrode
^G
=enthalpy change ΔHθ - T x change in entropy ΔSθ
% uncertainty
uncertainty of measurement x100
measurement
% atom economy
=mass of desired product (g) x100
total mass of reagents (g)
% yield
=actual mass of products x100
total hypothetical mass
Kp from Kc
Kc x (8.314 X temperature)^change in moles
