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."

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

ok whats the question if not i cannot you i need question and need a thing to answer
