1. At 25 oC, the second order rate constant for thereaction I- + ClO- ----> IO- +Cl- is 0.0805 M-1s-1. If asolution is initially 4.05 x 10-3 M with respect to eachreactant, what will be the concentration of each species presentafter 250 s? (Treat it as if there is only one reactant.)
2. A second order reaction whose rate constant at700 oC was found to be 4.0 x 10-3 L/mol.s hasan activation energy of 35.0 kJ/mol. What is the rate constant forthis reaction at 850 oC?
3. What change would you predict in the solubilityof N2(g) in water if the temperature changes from 20oC to 80 oC?
4. The osmotic pressure of a 0.82 M HClsolution is 35.9 atm at 18 oC. Calculate the van't Hofff actor for HCl at this concentration
