Question

a reaction between ethene and oxygen is used to produce epoxyethane. when silv is combined with ethene, the reaction for producing epoxyethane occurs much faster. what role does silver play in this chemical process? a) silver is a p - type semiconductor in this reaction. b) silver causes hydrolysis in this reaction. c) silver is an n - type semiconductor in this reaction. d) silver is a catalyst in this reaction.

Explanation:

A catalyst speeds up a chemical reaction without being consumed. Here, silver increases the reaction rate of ethene and oxygen producing epoxyethane, so it acts as a catalyst. Option A and C are incorrect as silver is a metal, not a semiconductor. Option B is incorrect as hydrolysis involves water, and this reaction is between ethene and oxygen.

Answer:

D. Silver is a catalyst in this reaction.
