Assertion (A): A flue gas analysis quoted on a dry basis gives higher percentages than the same gas on a wet basis.
Reason (R): Removing the water reduces the total against which each component is measured.

  • A.A is false but R is true
  • B.Both A and R are true, and R is the correct explanation of A
  • C.Both A and R are true, but R is not the correct explanation of A
  • D.A is true but R is false

Answer: B

Both are true and the reason gives the arithmetic: the same moles of carbon dioxide divided by a smaller total give a larger fraction, so the basis must always be stated with the figure. Dry basis figures are the ones usually quoted for flue gas.
