Which aqueous solution will have the highest freezing point?

What is the percent yield when 1.72 g of H2O2 decomposes and produces 375 mL of O2 gas measured at 42 oC and 1.52 atm?  The molar mass of H2O2 is 34.02 g/mol. 2H2O2(aq) → 2H2O(l) + O2(g)  

Which aqueous solution all at 25 oC will have the highest osmotic pressure?

The reaction of: 2N2O5(g) → 4NO2(g) + O2(g) is experimentally determined to be first order.  What experimental data would support this conclusion I. Plotting 1 / vs. time would be linear II. The half-life is independent of the initial concentration III. Doubling the initial concentration of N2O5 would yield a quadrupled initial rate.
