In which of the gases given below, the average speed of the molecule is the least at 1000K?
Speed is inversely proportional to molecular weight. Molecular weight of SO2 is highest among the four. Hence its speed is least.
Give the characteristic tests for the following gases: [5 MARKS]
(a) CO2 (b) SO2 (c) O2 (d) H2 (e) N2
