when will a reaction happen?
2 molecules must be in close proximity
correct part of the molecules must collide - with enough energy to react
steric factor
location of a collision matter
activation energy
minimum energy needed for a reaction to happen
breaks bonds in the reactants before new bonds can form in the products
enthalpy profiles
shows progress of reaction on x-axis and energy level on y-axis and contains:
relative enthalpies of reactants and products
activation energy of a reaction
overall enthalpy change of a reaction
