Question 1 : For the reaction A(aq) -- -> B(aq) the change in the standard free enthalpy is 2.92 kJ at 25 °C and 5.02 kJ at 45 °C. Calculate the value of this reaction's equilibrium constant at 75 °C. Question 2 : A container encloses 34.9 g of CO2(g). The partial pressure of CO2 is 2.15 atm and the volume of the container is 26.3 L. What is the average, or root mean square, speed (in m/s) of the CO2 molecules in this container? Question 3 : We have 500.0 mL of a buffer solution that is 0.633 M in NH3 and 0.332 M in NH,Cl. We add 500.0 mL of a solution 0.234 M in HCl. The final volume is 1.0000 L. The K, value for NH3 is 1.8 x 10-5. What is the pH of the final solution?
