b.It is a heterogeneous catalyst, so only a small amount is needed and it is easily separated from the products.
Explanation:
Platinum is best described as a heterogeneous catalyst in which only a small amount of it is needed and it can be easily separated from products.
A heterogeneous catalyst is a catalyst that exists in a different phase than the reactants.
A homogeneous catalyst is one that exists in the same phase as the reactants.
- A catalyst is a substance that speeds up the rate of chemical reactions.
- They help to lower the activation barrier for the reaction and are not used up.
- The reactants in the car exhausts are in the gaseous phases.
- Platinum is a solid metal.
- Therefore we can see that it is a heterogeneous catalyst.
