Multiplechoice questions may continue on the next column or page – find all choices before answering. d [A] a dt = k [A] = [A] akt t 1 / 2 = [A] 2 ak d [A] a dt = k [A] ln[A] = ln [A] akt t 1 / 2 = ln 2 ak d [A] a dt = k [A] 2 1 [A] = 1 [A] + akt t 1 / 2 = 1 ak [A] ln a b = ln a ln b rate = k [A] x [B] y = 1 a × d [ A ] dt k = A exp parenleftbigg E a RT parenrightbigg ln k 2 k 1 = E a R parenleftbigg 1 T 1 1 T 2 parenrightbigg 001 5.0 points Express the rate of the following reaction in terms of the [NaOH]. C 2 H 4 Br 2 +2 NaOH→ C 2 H 2 +2 NaBr+2 H 2 O 1. rate = Δ[NaOH] Δ t 2. rate = Δ[NaOH] 2Δ t 3. rate = Δ[NaOH] 2Δ t correct 4. rate = 2Δ[NaOH] Δ t 5. rate = 2Δ[NaOH] Δ t Explanation: rate = [C 2 H 4 Br 2 ] Δ t = [NaOH] 2Δ t = [C 2 H 2 ] Δ t = [NaBr] 2Δ t = [H 2 O] 2Δ t 002 5.0 points Consider the combined Arrhenius equation....
