WebBetween experiments 2 and 3, [B] stays the same and [A] is quadrupled, but the initial reaction rate stays the same. This means that the initial reaction rate is not dependent on [A], so the reaction is zero order with respect to A. (May also justify using mathematics as shown in part (b).) One point is earned for the correct order and for the Webmore. This is grade-12/college-level but if you're curious I will show you below. So for a first order reaction -- we have the reaction equals the rate constant times the concentration of the (only) reactant --> R = k [A] 1. Then we choose to re-write R as -Δ [A]/Δt. and we get -Δ [A]/Δt = k [A] 2. Then we bring -Δt to the right side.
