what do you call the gap between the s and p energy bands? (hint: band theory of solids)
forbidden zone
the energy released when one mole of a formula unit is produced by bonding together multiple gas atoms
crystal lattice energy
heisenberg uncertainty principle
the product of the uncertainties in the momentum and the position of a particle equals h/(4π) or more
demonstrated that rate constants vary with temperature
Svante Arrhenius
hypothetical species between reactants and products
activated complex
reaction step with rate law that corresponds to molecularity of reaction
elementary reaction
chemical species consumed in an elementary step and produced in another
intermediates
acids in bronsted lowry theory
proton donors
meaning of pH
potential of hydrogen
strengths of acids along a row
more polar = stronger acid
acid trends for same group
longer bond = stronger acid
effect of second substance that contains the same ions that can participate in equilibrium
common ion effect
when Q > Kc
system trends towards reactants
when Q < Kc
system trends towards products
describe the salt effect
uncommon ions increase solubility
where oxidation occurs
anode
where reduction occurs
cathode
describe the cell diagram
anode | oxidation HF || reduction HF | cathode
E cell equals?
Ecell = E right - E left
E cathode - E anode
E reduction - E oxidation
describe gibbs energy of electrochemical cell
delta G = -zFEcell
describe relationship of Ecell and K
Ecell = RT/zF lnK
describe relationship of Ecell and K
Ecell = RT/zF lnK
root mean square velocity
V = sqrt (3RT/MW)
