Part 1: Research and DESCRIBE what makes transition metals good catalysts.
HINT: Make reference to their electrons in the 3d shell. Post the link/s that you used to write your description.

Part 2: Catalysts are of homogeneous type and heterogeneous types.
Research to find out what is the difference between the two and STATE the difference in the post.
Extend your research to find a suitable picture/image that demonstrates a homogeneous and heterogeneous catalyst.

Part 1:

transition metals are good catalysts because they have partially filled d orbitals meaning that they are able to quickly gain or lose electrons with the reactants giving an easier way for the reaction to take place with a lower activation energy

Part 2:

a homogenous catalyst means that the catalyst is in the same state as the reactants.

a heterogeneous catalyst is when the catalyst is in a different state to the reactants.

Part 1:

they have incompletely filled d-orbitals which allow them to donate or accept electrons easily from other molecules

Part 2:

Heterogeneous catalyst:

catalysts that exists in a different phase than the reaction mixture, typically as a solid, this means that it can increase in catalytic activity through the the absorption of reactant into their active site. e.g. the interaction of hydrogen gas with the surface of a metal, such as Ni, Pd, or Pt.

Homogeneous catalyst:

catalysts that operate in the same state as the the reactants without a phase boundary, for example, liquid acids, alkali catalysts, and soluble transition metal compounds.
