WebJun 18, 2024 · The following three lines are what NOT to do: r2(t) r1(t) = ([B]2 [B]1)n = ( 0.1 0.1)n = 1n ⇒ ln( 4.0 × 10−4 2.0 × 10−4) = ln1n = nln1 Therefore, n = ln2 ln1 = 0. The error here is in choosing the wrong reactant terms to cancel out in the rate law; A did vary, so it does not go to 1 for arbitrary orders.
