A gas is dissolved in a liquid under conditions where Henry's law is valid. Which change would most directly require using a new value of $K_H$ even for the same gas-liquid pair?
AChanging the temperature
BChanging the amount of liquid without changing composition
CStirring the solution faster
DChanging the shape of the container
Answer & Solution
Correct answer: A. Changing the temperature
Henry's law constant depends on temperature. For the same gas-liquid pair, changing temperature changes $K_H$, whereas merely changing container shape or stirring does not define a new equilibrium constant value.
