define a catalyst
provides an alternative pathway at lower activation enthalpy
1 of 8
what is a homogeneous catalyst?
where the catalyst and reactant are both in the same physical states
2 of 8
what is a heterogeneous catalyst?
where the catalyst and reactant are in different physical states
3 of 8
name the 4 key steps for heterogeneous catalysis
1. adsorption of reactants onto the surfaces of the catalyst 2. bonds between the reactants weaken and break 3. new bonds form beween the newly formed products 4. product diffuses away

what is hydrogenation?
a chemical reaction of the addition of hydrogen to simple substances (elements) or chemical compounds
5 of 8
describe isotactic
where all the substituted carbons have the same stereochemical configuration
6 of 8
define syndiotactic
where all the substituted carbons have alternating stereochemical configurations
7 of 8
define atactic
