Question

Consider the following mechanism, in which A, B, and B may be elements, or compounds, and C, D and F are compounds:

(1) 2A + B → C
(2) C → D
(3) D + E → F

Which step is most likely to be the rate determining step? Explain.

I know that the rate determining step is the slowest step of a chemical reaction and it determines the rate of the overall chemical equation, but the thing is the rate of the overall process is not given and they did not mention which one of them is fast or slow, so how will i know which one is the rate determining step?

Answer 1

If it is not showing properly, here it is:

Answer 2

I am not really sure, but if you recall the reaction pathway diagram, the C is the one suffering most transformations, meaning at first A and B react to form C and C itself undergoes the next reaction, probable an endothermic reaction tonultimately form F. In other words, the C had to formed and then form an ion which would eventually bind with another element to for a coumpound.

Answer 3

can you show me a pathway diagram for this?

Answer 4

Those curves mean reaction.

Answer 5

aah i get it, thank you ^_^

Answer 6

You are welcome.
