Q1: Pick out the wrong statement

ANS:D - In actual practice, absorption is an en-dothermic process, while stripping is an exothermic process.

The wrong statement is: In actual practice, absorption is an endothermic process, while stripping is an exothermic process. In actual practice, absorption is typically an exothermic process where heat is released as the solute is absorbed into the solvent. Stripping, on the other hand, is generally an endothermic process where heat is absorbed as the solute is removed from the solvent. This is because during absorption, the solute is usually at a higher concentration in the gas phase than in the liquid phase, resulting in heat release upon dissolution. Conversely, during stripping, the solute is usually at a higher concentration in the liquid phase than in the gas phase, requiring heat input to remove it from the solvent. Therefore, the statement provided is incorrect.
