For this question imagine that sea water is a 3.5 mass % solution of NaCl with a density of 1.00g/mL. Assume full dissociation of the NaCl.
a) Calculate the freezing point of sea water.Briefly explain why it is not 0 (degrees Celsius).
b) Calculate the osmotic pressure of sea water at 298K. Briefly explain how this relates to the desalination of sea water via reverse osmosis.
The isomerization of methyl isocyanide, CH3NC -> CH3CN, follows first-order kinetics. The half-lives were found to be 161 min at 199 degrees celcius and 12.5 min at 230 degrees celcius. Calculate the activation energy for this reaction.
