why does platinum metal make a good catalytic surface for reactant molecules?\nit causes reactant molecules to be less reactive.\nit strengthens bonds between reactant molecules.\nit prevents products from breaking away from the surface.\nit holds reactant molecules in a good position for them to react.
Answer
Brief Explanations:
A catalyst's role is to speed - up a reaction by providing an alternative reaction pathway with a lower activation energy. Platinum as a catalyst holds reactant molecules in an optimal orientation, facilitating the reaction. It doesn't make reactants less reactive, strengthen bonds between reactant molecules, or prevent products from leaving the surface.
Answer:
It holds reactant molecules in a good position for them to react.
