WebThe physical reason for this is that when most gases dissolve in solution, the process is exothermic. This means that heat is released as the gas dissolves. This is very similar to the reason that vapor pressure increases with temperature. Increased temperature causes an increase in kinetic energy. WebOrganic products exposed to environmental contaminants risk undergoing chemical reactions, involving an increase in temperature. These exothermic reactions can lead to product degradation and inevitably introduce explosion risks. Another problem especially in multi-silo plants is the complex gathering of the single monitoring data from each ... WebSolutions. ( 1) The kinetic energy of the molecules is directly dependent on the temperature of the system. The rate of a chemical reaction depends on the number of effective collisions which increases with increasing the temperature of the system.
