What happens to the rate if dissolution as the temperature is increased in a gas solution

Hi there!❤

Mixing of gases in liquids is an exothermic process,i.e., energy is released in this process. So, according to Le-Chatelier's principle, dissolution of gases in liquids are preferred in low temperature. When the temp. is increased, the rate of dissolution will decrease and may also proceed in the opposite direction.

the answer for sodium is 0.186

the answer for rubidium is 0.251

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
