Question

Equal moles of each of `SO_(3), CO_(2)O_(2)` and `H_(2)` are kept in a container. A hole is made in the container and gasses are allowed to effuse. After 5 minutes the order of partial pressure of each gas in the container would be :
A. `SO_(3)gt CO_(2)gt O_(2)gt H_(2)`
B. `SO_(3)gt O_(2)gt CO_(2)gt H_(2)`
C. `H_(2)gt O_(2)gt CO_(2)gt SO_(3)`
D. `H_(2)gt O_(2)gt SO_(3)gt CO_(2)`

Answer 1

Correct Answer - A
Equal moles of each of ……………
Lighter gas will effuse more. More amount of heavler gas will remain in the container. So more partial pressure in the container will be heavier gas.
