Answer to Question #204419 in General Chemistry for emily

Question

is there a catalyst in sunscreen/is it a catalyst? if yes, then what, & how does it speed up the reaction? idk

Answer 1

A catalyst lowers the activation energy so that molecules with low energy can easily participate in the chemical reaction and hence product formation becomes faster. Thus, we can conclude that the statement it lowers energy requirements best describes an effect of using a catalyst in an industrial process.
