1. Br₂ water
2. H₂N-OH
3. (CH₃CO)₂O

The rate of a reaction quadruples when the temperature changes from 293 K to 313 Κ. Calculate the energy of activation of the reaction assuming that it does not change with temperature.

Henry’s law constant for CO₂ in water is 1.67 x 108 Pa at 298 K. Calculate the quantity of CO₂ in 500 mL of soda water when packed under 2.5 atm CO₂ pressure at 298 K.

Write down the IUPAC name for the following complex and indicate the oxidation state, electronic configuration and coordination number. Also give stereochemistry and magnetic moment of the complex:
Cs[FeCl₄]

Concentrated nitric acid used in laboratory work is 68% nitric acid by mass in aqueous solution. What should be the molarity of such a sample of the acid if the density of the solution is 1.504 g mL^-1?

100 mg of a protein is dissolved in just enough water to make 10.0 mL of solution. If this solution has an osmotic pressure of 13.3 mm Hg at 25°C, what is the molar mass of the protein? (R = 0.0821 L atm mol^–1 K^–1 and 760 mm Hg = 1 atm.)
