molecular energies in a gas are expressed on a →
Maxwell Boltzmann Distribution
y - axis
number of particles
x axis
kinetic energy
why does the curve begin at the origin?
0 particles have 0 energy
highest point on the curve
most probable energy
second highest point on the curve
mean energy
lowest point on the curve
activation energy
changing reaction conditions =
shape of curve alters
-number of particles with energy greater than Ea is different
-total area under curve = total number of molecules in sample, so must remain constant
