Web27 feb. 2024 · Henry's law is a gas law formulated by the British chemist William Henry in 1803. The law states that at a constant temperature, the amount of dissolved gas in a volume of a specified liquid is directly proportional to the partial pressure of the gas in equilibriumwith the liquid. WebThe Eyring equation (occasionally also known as Eyring–Polanyi equation) is an equation used in chemical kinetics to describe changes in the rate of a chemical reaction against temperature. It was developed almost simultaneously in 1935 by Henry Eyring, Meredith Gwynne Evans and Michael Polanyi.

WebThe relevant equation here is c = k H P. We rearrange and solve to get the Henry's Law constant: To get the solubility at 25.5 mm Hg, we use the above constant, use the correct units, and rearrange: Problem 11.72: Look at the solubility graph in Figure 11.7 and estimate an approximate Henry's-law constant for xenon at STP. There are many ways to define the proportionality constant of Henry's law, which can be subdivided into two fundamental types: One possibility is to put the aqueous phase into the numerator and the gaseous phase into the denominator ("aq/gas"). This results in the Henry's law solubility constant … Meer weergeven In physical chemistry, Henry's law is a gas law that states that the amount of dissolved gas in a liquid is directly proportional to its partial pressure above the liquid. The proportionality factor is called Henry's law constant. It … Meer weergeven In production of carbonated beverages Under high pressure, solubility of CO 2 increases.
