WebThat is, we are stating that ratio of Henry's constants approximates to the ratio of equilibrium constant because we assume that only ratio of pressure is significant and other ratios tend to unity. This is, off course, not always acceptable, but in some restrained conditions it might hold. Webenry’s law and the Henry’s constant are widely used in chemical and environmental engineering. Unfor-tunately, many people do not appreciate that the Henry’s “constant” is not a true constant, but instead has a significant non-linear temperature dependence. Ignoring this temperature dependence can lead to serious inaccuracies.

WebHenry’s law constant can also be expressed as the dimensionless ratio between the aqueous-phase concentration c a of a species and its gas-phase concentration c g: kcc H … WebSolubility of a gas in a liquid, according to Henry’s law, is directly proportional to the gas’s pressure. We change the proportionality constant into KH in order to change it. KH is determined by the nature of the gas, the liquid, and the temperature (T). As the temperature rises, ‘KH’ increases, and X decreases. crystal habit of copper

It is because K h is inversely proportional to solubility and as we increase temperature solubility decreases and hence K h value should increase. But the correct answer is value of K h also decreases with increase in temperature. crystal haarentferner
