Why does platinum metal make a good catalytic surface for reactant molecules? it causes reactant molecules to be less reactive. it strengthens bonds between reactant molecules. it prevents products from breaking away from the surface. it holds reactant molecules in a good position for them to react.

The right answer is "It holds reactant molecules in a good position for them to react."

Explanation:

Catalysts are a substances that increase the reaction rate by lowering the activation energy (Eₐ) by providing an alternative (lower-energy) pathway for the reaction to take place .

The catalyst increases the frequency of collisions between reactants this done by holding reactant molecules in a good position for them to react.

So, The right answer is "It holds reactant molecules in a good position for them to react."

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.
