Verified step by step guidance

Understand the concept of reaction rate: The initial reaction rate is the change in concentration of a reactant or product per unit time. It is typically expressed in molarity per second (M/s).

Convert units where necessary: Ensure all concentrations are in the same units. Here, [A] i is given in molarity (M) and [A] f is given in millimolar (mM). Convert [A] f from mM to M by dividing by 1000.

Calculate the change in concentration of A: Use the formula Δ[A] = [A] i - [A] f, where [A] i is the initial concentration and [A] f is the final concentration after the given time.

Determine the time interval: The time interval given is 0.01 μsec. Convert this to seconds by multiplying by 10^-6.

Calculate the initial reaction rate: Use the formula rate = Δ[A] / Δt, where Δ[A] is the change in concentration and Δt is the change in time. Substitute the values obtained from the previous steps to find the initial reaction rate.
