Question

Which statement below best describes the relationship of the reaction below?

3A + B yields 2AB


A. For every AB produced, the reaction requires three A.


B. The rate of formation of AB is twice the disappearance of A.


C. For every two AB produced, the reaction requires three A.


D. The rate of disappearance of A is two times the formation of AB.

Answer 1

It is C

Step-by-step explanation:

A) does not make sense because we obviously see that it has 2 moles of AB (right side of equation) for every 3 moles of A (left side of equation). We do not have data to prove B) is correct. It would require data actually. We also do not have data to prove that D is true either. But, we do know based on the equation that "for every two AB produced, teh reaction requires three A."

Answer 2

For every two AB produced, the reaction requires three A
