physisorption is an exothermic reaction.so according to le chatlier's principle,as temperature increases,backward reaction is favoured
What else can I help you with?
Why physisorption decreases with increase in temperature?
Physisorption is exothermic in nature. Therefore, in accordance with Le-Chateliere's principle, it decreases with an increase in temperature. This means that physisorption occurs more readily at a lower temperature.
Why does physisorption decreases with increase in temperature?
Physisorption decreases with an increase in temperature because at higher temperatures, molecules in the gas phase have more kinetic energy. This increased kinetic energy makes it more difficult for the gas molecules to be adsorbed onto the surface of the adsorbent material. Additionally, higher temperatures can disrupt the induced dipole-dipole interactions that are responsible for physisorption.
How does increasing the temperature of a gas solvent affect the solubility of a gas?
Increasing the temperature of a solvent decreases the solubility of a gas Generally, increasing solvent temperature decreases the solubility of gases.
The rate at which temperature decreases with increasing altitude is known as?
The rate at which temperature decreases with increasing altitude is known as the lapse rate.
How does increasing temperature affect the solubility of a gas solute?
Increasing temperature decreases the solubility of a gas solute in a liquid solvent. This is because higher temperatures increase the kinetic energy of molecules, leading to weaker gas-liquid interactions and reduced solubility.
Why does physisorption decrease with the increase of temperature?
Physisorption is weaker than chemisorption and is typically dependent on van der Waals forces. As temperature increases, the thermal energy disrupts these weak interactions between the adsorbate and the surface, leading to a decrease in physisorption.
What is the difference between metal and semiconductor?
A semiconductor's resistivity decreases with increasing temperature. A metal's resistivity increases with increasing temperature.
How the atmosphere vary with altitude?
Temperature decreases with increasing altitude, Also air concentration decreases with altitude.
The density of water depends on its?
Pressure and temperature. Increasing the pressure increases the density. Increasing the temperature decreases the density between melting point and 4oC
Why Energy activation decreases by increasing temperature?
Increasing temperature provides molecules with more kinetic energy, increasing the likelihood of successful collisions to activate a reaction without the need for external energy input. As a result, the activation energy required decreases at higher temperatures, making the reaction more favorable and faster.
In the troposphere and mesosphere what happens to temperature as altitude increases?
In the troposphere, temperature typically decreases with increasing altitude due to the adiabatic cooling effect. In the mesosphere, temperature increases with altitude due to absorption of solar radiation by ozone molecules.
How can you decrease the preassure without increasing the area?
we can chang the temperature,decreasing the temp. presure is also decreases
