Question

Part 2. Short answer questions 1) A and B are volatile liquids. In the figure below, the partial pressure of A and B in a liquid solution of these two substances (at T-40. "C) is plotted against the mole fraction of A in the liquid solution po 300 200 100 00 02 10 04 06 mole fraction A a) Do A and B form an ideal liquid sokution (yes/no)? (4 points) b) What is the value for poº, the vapor pressure of pure liquid B, at T - 40.0°C? [6 points) 2) For the chemical reaction COAS)+H30(0 = H2CO (aq) give the correct expression for Ko, K., and K, or explain why such an expression cannot be given. [12 points) 3) Give the formation reaction for rubidium hydrogen carbonate (RbHCO,(6)). [6 points) 5

Answer 1

1) a) since linear graph is given ,we can say it follows raults law, hence they form ideal solution

Yes

B)
