For the reaction 5  Br – aq   +  BrO 3 − aq   +  6   H + aq → 3   Br 2 aq   +   3   H 2 O  l the rate expression was found to be – d B r O 3 – d t = k B r – H + 2 B r O 3 - Which of the following statements is /are correct? I. Doubling the initial concentration of all the reactants will increase the reaction rate by a fa

Options

  1. AI and II
  2. BII and III
  3. CII and IV
  4. DIII only

Correct answer

D. III only

Step-by-step solution

r = – d BrO 3 − dt = 1 3 d Br 2 dt r = K B r - H + 2 B r O 3 - r ′ = K 2 B r - 2 H + 2 2 B r O 3 - =16r
