Solution

Sure, here are the answers to your questions:

  1. The answer is D. 273 K. This is because, according to Charles's Law, the volume of a gas is directly proportional to its temperature in Kelvin. So, if the volume doubles, the temperature will also double. The temperature at 0oC is 273 K, so if it doubles, it will be 2*273 = 546 K. However, the question asks for the change in temperature, which is 546 - 273 = 273 K.

  2. The answer is A. mol2dm-6 S-1. The rate equation is Rate = K [A]2. The units of rate are mol dm-3 s-1 and the units of concentration [A] are mol dm-3. Therefore, to make the units on both sides of the equation equal, the units of the rate constant K must be mol2dm-6 S-1.

  3. The answer is C. Promoter. A promoter is a substance that, while not itself a catalyst, increases the activity of a catalyst.
