# Average Reaction Rates

## Homework Equations

Δ[A]/aΔt = Δ[ B]/bΔt

## The Attempt at a Solution

Δ[ I]/3Δt = Δ[H]/2Δt = 7.8E-4. What exactly am I supposed to do for this?

Δ/3Δt = Δ[H]/2Δt = 7.8E-4
I don't understand what you calculate here, and the number you get there (which is not the answer) doesn't agree with the number you put into the form (which is also not the answer).

Part B works in the same way as part A.

What I did in part A was divide 7.8E-4 by 3. However I am unsure what this is fundamentally doing apparently as I can not understand how to get part B. Do I divide 7.8E-4 by 2?
