Maxwell-Boltzmann distribution Flashcards
What is Maxwell-Boltzmann distribution?
shows the energy of the particles
graph that shows the energy against the fraction of particles
end up with a Maxwell-Boltzmann distribution curve
What are the rules for the curve?
no particles have 0 energy
most particles have intermediate energies, around the peak of the curve
few have high energies
there is no upper limit, never touches the x axis
most probable energy =/= average energy
What does the area right of the activation energy on a M-B distribution curve?
the number of particles with enough energy to break bonds
What is the effect of temperature on the curve?
peak is lower
moves to right
number with high energy increases
total area is the same
more p[araticles have the Ea
What is activation energy
minimum energy to start a reaction
most molc have less energy than the activation energy
at a constant temp, why does eventually the substance decompose?>
molc gain energy due to collisions
What is the area under the curve represent
total number of molc
