There are two closed containers A and B. Container A contains `PCl_5` gas at `25^@C` temperature and 1 bar pressure. Container B contains 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 .
