The Chemical Engineering Theory section is now launching a \"One Question per Day\" activity to help everyone reinforce their basic knowledge in chemical engineering. Subsequent series such as \"Principles of Chemical Engineering,\" \"Mass Transfer and Separation,\" \"Thermodynamics in Chemical Engineering,\" and \"Chemical Process Engineering\" will also be introduced. We hope for your active support! Answers to the questions in the \"One Question per Day\" activity can be viewed directly, and the thread will be closed after 1 day! ! Participation earns 2 wealth points, with an additional 3 wealth points for correct answers~~~ Multiple-choice question: In the operation of countercurrent absorption at low concentrations, if all other operating conditions remain unchanged and only the amount of gas fed into the tower is increased, then the total mass transfer unit height of the gas phase will ( ) ； The total number of mass transfer units in the gas phase will ( ). A. Increase ； B. Reduce ； C, unchanged ； D、Uncertain ； AB
