For four gases vander - waal's constants a & b are given as followingGas a(PaLt2 mol-2)b(Lt mol-1)A6500.0051B1550.0049C4500.0051D1550.049Between gas A & C which has higher volume and between gas B & D which has higher compressibility?(1) A.B(2) A, D(3) C, B(4) C, D |

Answer» The correct option (3) C, B Explanation: For gases A & C,'b' value is same so gas having value of 'a' i.e. higher force of attraction will have lesser volume. Gas C will have higher volume. For B & D, 'a' value is same, so gas having higher value of 'b' will be less compressible ∴ Z = 1 - a/VRT + Pb/RT ∴ Gas B will be more compressible |
