question 6 (1 point)
consider the potential energy diagram below, which represents a chemical reaction with a
multistep reaction mechanism.
which of these steps would most likely be the rate determining step?
c - d
a - b
b - c

Explanation:

In a potential energy diagram for a multi - step reaction, the rate - determining step is the step with the highest activation energy. The activation energy is the energy difference between the reactants (or the intermediate for subsequent steps) and the transition state of that step. Looking at the diagram, the step A - B has the highest peak (transition state) compared to the other steps (B - C and C - D).

Answer:

A. A - B
