There are two closed containers A and B Container A contains PCl_3 gas at 25^@C temperature and 1 bar pressure. Container B contain equilibrium mixture of gases obtained by partial decomposition of PCl_(5) (g) at the same temperature and pressure. Assuming that initially equal mole of PCl_(5) (g) at same temperature and pressure . Assuming that initially equal moles of PCl_(5) were taken into the containers ( before decomposition ), the gases are allowed to effuse through a pinhole in the containers, Which container will show higher rate of effusion ? Justify .
