0.5 mole of each of H ₂, SO ₂ and CH ₄ 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

Step-by-step solution

Rate of diffusion 1 molecular mass Order of diffusion : H ₂> CH ₄> SO ₂ and amount left is in the order SO ₂> CH ₄> H ₂ Hence, order of partial pressure is pSO ₂> pCH ₄> pH ₂
