Question

Refer to the following:
The reaction: 2A + B --> 2C Rate = k[A]^2.

A different proposed mechanism for the reaction above is:
Step 1 A <=> D
Step 2 D + A --> E
Step 3 E + B --> F
Step 4 F --> 2C

In the mechanism above, D, E, and F are:

A. products only.
B. reactants only.
C. transition states.
D. intermediates.

Answer 1

@aaronq Please help me!

Answer 2

It is A right?

Answer 3

that is incorrect.

the product is C

Answer 4

2C is the product?

Answer 5

yep

Answer 6

So then what are D, E, and F? @aaronq

Answer 7

If the overall reaction is \[2A + B \rightarrow 2C\] and substances D, E, and F DON'T APPEAR in the overall reaction, can they be either reactants or products?

Answer 8

Ohh no. So D E and F are not reactants or products. Is the answer C?

Answer 9

substances D, E, and F are formed in one step, then immediately used in the next step. They can't be reactants or products

Answer 10

transition states aren't written in reaction steps

Answer 11

So it's D then.

Answer 12

they are intermediates

Answer 13

Thank you so much! :)
