    Part I

    5 x 2 = 10
  1. Define average rate and instantaneous rate.

  2. Define rate law and rate constant.

  3. Derive integrated rate law for a zero order reaction A\(\longrightarrow \) product.

  4. What is the order with respect to each of the reactant and overall order of the following reactions?
    a) 5Br-(aq)+BrO3-(aq)+6H+(aq) ➝3Br2(l)+3H2O(l)
    The experimental rate law is Rate = k [Br][BrO3][H+]2
    b) CH3CHO(g)\(\overset { \Delta }{ \longrightarrow } \) CH4(g)+CO(g) the experimental rate law is
    Rate =K[CH3CHO]\(\frac{3}{2}\)

  5. The rate of the reaction X + 2y→ product is 4 x 10-3 mol L-1S-1, if [X] = [Y] = 0.2M and rate constant at 400K is 2 x 10-2s-1, What is the overall order of the reaction.
