- For the reaction BrO3- + 3SO32- Br- + 3SO42-
a. At what rate are sulfate ions (SO42-) being produced if the sulfite ion (SO32-) is
disappearing at a rate of 2.4×10-4 mol/L·s?
b. Predict the rate law if the reaction rate is tripled when [BrO3-] is tripled and the reaction
rate is doubled when [SO32-] is doubled.
c. What is the overall order of reaction based on your predicted rate law?
- Polonium (Po) is the only metal known to crystallize in a simple cubic structure. If the X-ray
experiment shows that the radius of a polonium atom is 330.2 pm in a unit cell, what is the
volume of a polonium unit cell in cm3?
