Which oF the Following correctly expresses the rate oF change oF [B] ? 1. Δ[B] Δ t = - 2 (rate oF rxn) 2. Δ[B] Δ t = +(rate oF rxn) 3. Δ[B] Δ t = - (rate oF rxn) 4. Δ[B] Δ t = - 1 2 (rate oF rxn) 5. Δ[B] Δ t = +2 (rate oF rxn) 6. Δ[B] Δ t = + 1 2 (rate oF rxn) 004 10.0 points Suppose a compound is involved in three di±erent reactions denoted R 1 , R 2 , and R 3 . Tripling the concentration oF this reactant in all three reactions causes the rates oF reaction to increase by Factors oF 3, 9, and 1, respec- tively. What is the order oF each reaction with respect to this reactant? 1.
