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."

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

consider the reaction below.
