Interpretation of a Reaction

APCHEM-QUXUE1

The following reaction:

$$C_2H_5OH \rightarrow C_2H_4O + H_2$$

...occurs in a copper reaction chamber. The graph of [Ethanol] versus time is a straight line with a negative slope. This is an elementary, single step reaction.

Based on the information, which of the following is NOT true?

A

Copper must be a heterogeneous catalyst since the material used for the reaction chamber was specifically mentioned.

B

A straight line plot of [reactant] vs. time with a negative slope indicates that the reaction is zero order.

C

An intermediate will be formed during the reaction since there is one reactant and two products.

D

For this reaction, the rate law can be determined from the graph and the balanced equation because the reaction is a single-step, elementary reaction.
