Document Summary
R = 8. 314 j/molk = 0. 08206 l atm/molk (5) Sulfur dioxide reacts with oxygen in the presence of platinum to give sulfur trioxide: Suppose that at one stage in the reaction, 26. 0 mol so2, 83. 0 mol o2 and 17. 0 mol so3 are present in the reaction vessel at a total pressure of 0. 950 atm. Calculate the mole fraction and partial pressure of each gas. 2 so2 (g) + o2 (g) 2 so3 (g) 1 atm = 760 torr = 101. 325 kpa. The solubility of a gas is 0. 0010 g/100 g h2o at 25 c and 1 atm. The identity of the gas must be known to answer this question. Circle the letter beside your choice and justify your answer in 2-3 sentences. Circle the letter beside your answer and justify your answer in 2-3 sentences. Explain the following observation: a can filled with steam at 100 c and atmospheric pressure collapses when sealed and cooled. (3) (3) (3)
