From the given set of statement/data : (A) Normal boiling point means boiling point at 1 atm pressure (B) Standard boiling point means boiling point at 1 bar pressure (C) At ( STP (0^ C . ) and 1 bar pressure) molar volume is 22.4 L of an ideal gas (D) At SATP ( (25^ C . ) and 1 bar pressure) molar volume is 22.4 L of an ideal gas The correct statement is :

Options

  1. AA only
  2. BD only
  3. CB, C and D only
  4. DA, B and C only

Correct answer

D. A, B and C only

Step-by-step solution

- (A) is correct: Normal boiling point refers to the boiling point of a liquid at 1 atm pressure. (B) is correct: Standard boiling point refers to the boiling point at 1 bar pressure. (C) is correct: At STP ( (0^ C ) and 1 bar), the molar volume of an ideal gas is approximately 22.4 L. (D) is incorrect: At SATP ( (25^ C . ) and 1 bar), the molar volume of an ideal gas is approximately 24.789 L, not 22.4 L. Hence, only A, B, and C are correct.
