Gas pressure increasing physical or chemical
WebFeb 16, 2024 · Increasing the amount of space available will allow the gas particles to spread farther apart, but this reduces the number of particles available to collide with the container, so pressure decreases. WebDefinition. The relative activity of a species i, denoted a i, is defined as: = where μ i is the (molar) chemical potential of the species i under the conditions of interest, μ o i is the (molar) chemical potential of that species under some defined set of standard conditions, R is the gas constant, T is the thermodynamic temperature and e is the exponential constant.

WebAn example. In the manufacture of ammonia by the Haber Process, the rate of reaction between the hydrogen and the nitrogen is increased by the use of very high pressures. In fact, the main reason for using high pressures is to improve the percentage of ammonia in the equilibrium mixture, but there is a useful effect on rate of reaction as well. WebThe activity of pure substances in condensed phases (solid or liquids) is normally taken as unity(the number 1). Activity depends on temperature, pressure and composition of the …
