Question

The volumes of gases H2, CH4, CO2 and NH3 adsorbed by 1 g of charcoal at 288 K are in the order

  1. straight H subscript 2 greater than CH subscript 4 greater than CO subscript 2 greater than NH subscript 3
  2. CH subscript 4 greater than CO subscript 2 greater than NH subscript 3 greater than straight H subscript 2
  3. CO subscript 2 greater than NH subscript 3 greater than straight H subscript 2 greater than CH subscript 4
  4. NH subscript 3 greater than CO subscript 2 greater than CH subscript 4 greater than straight H subscript 2

The correct answer is: NH subscript 3 greater than CO subscript 2 greater than CH subscript 4 greater than straight H subscript 2
