0.5 mole of each of H2, SO2 and CH4 are kept in a container. A hole was made in the container. After 3 h, the order of partial pressures in the container will be (KCET 2009) (a) SO CH H P P P (b) H SO CH P P P (c) H CH SO P P P (d) SO H CH P P P

According to Graham's law of diffusion, rate of diffusion 1 partial pressure molecular mass Since, equal moles of all gases were taken in the Container, the rate of diffusion will be in the order H2 > CH4 > SO2 The order of partial pressure of the gases remaining in the Container will be 2 4 2 SO CH H P P P
