  1. QQ2.. For a reaction, the time required for 20% completion in 40 minutes, and 40% completion in 80 minutes. Find the order of reaction and rate constant.
  2. QQ2. 1(a). Discuss the theory of unimolecular reactions.
  3. QQ2. 1(b). Write short notes on molecularity, density, viscosity, and apparent molal volume.
  4. QQ2. 1(c). A + B + C = Products. When the container's volume is doubled, the reaction rate decreases 8 times. When [A] is doubled and [B] is halved then the rate of reaction increases 4 times. When [C] is four times alone, the reaction rate increases 64 times. Write the rate law of expression and find the order of reaction.
