| 3 | Two gas burettes, one containing 10cm3 of sulphur dioxide (SO2) and the other containing 30cm3 of hydrogen sulphide (H2S) both at 1 atmosphere and at 0oC are initially separated by a stop cork. The stop cork is then opened and the two gases are allowed to mix according to the reaction SO2(g) + 2H2S(g) →3S(s) + 2H2O(l). Calculate the final pressure (in atmospheres) after the reaction has ended and the apparatus has gained its temperature of 0oC. (Assume liquid water does not exert pressure).
