Answer:

Option C. Silver is a catalyst in this reaction.

Explanation:

From the question given, we discovered that the addition of silver in the reaction between ethene and oxygen produces epoxyethane at a much faster rate. This simply means that silver act as a catalyst in this reaction.

A catalyst is substance that increases the rate of a reaction without itself taking part in the reaction. The catalyst creates an alternate path way by lowering the activation energy so that the reaction can proceed at a much faster rate.

Since the addition of silver makes reaction to occur at a much faster rate, it therefore means that silver act as a catalyst in the reaction.

weeeeeb [17]

Answer:

Br_2

Explanation:

The compound X_2 is Br_2.

The reaction included are:

Br_2+NaCl--> No\ reaction  (because  bromine is less reactive than chlorine)

But , because of hexane the solution get dilute and its color changes to orange.

Now, NaI is added and we know Br is more reactive than I.

Therefore it replace it.

Reaction: Br_2+NaI-->NaBr+I_2

Purple color develop due to formation of Iodine.
