Question

Which statement best describes the diagram please help

Answer 1

Answer:

The right statement is " the Pathway A-C-D involves a catalyst and is faster than A-B-D"

Explanation:

Catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy Eₐ (i.e. by changing the reaction pathway), which Catalyst is not consumed in the catalyzed reaction and can continue to act repeatedly.

From the attached figure one can see that the path way A-C-D has different pathway and lower activation energy (Eₐ) than the pathway A-B-D, this means that the pathway A-C-D is a catalyzed pathway and it is faster than A-B-D.

So, the right statement is " the Pathway A-C-D involves a catalyst and is faster than A-B-D"
