Question
TE Physical adsorption is highly dependent on irregularities in the nature of the surface. Biochemical catalysts are mostly solids, and usually aim to cause the high temperature rupture or synthesis of materials Equilibrium between solid surface and physisorbed gas molecules is rapidly attained and easily reversible, because the energy requirements are small. 7.TF Biochemical catalysts are mostly solids, and usually aim to cause The energy of activation for reactions involving chemisorbed molecules is less than that for reactions involving gas-phase molecules alone. Desor ption is the process of removing an adsorbent from the ype ot energy involved. 1S. T Phere is no correspondence between rate equation and stoichionctric equation of an elementary reaction Cl F | For the reaction 2A+1B -R, the rates of reaction with respect to A, B and R are related to each otlher as to to A, B and R are related to each other as follows explain the answers.Explanation / Answer
9. True
In physical adsorption , there is just interaction between adsorbate and adsorbent and the irregularities of the adsorbent are the sites where the adsorbate will be adsorbed.
So, more the irregularities higher will be the physical adsorption .
7. The aim of the catalyst is to speed up the reaction, also the biochemical catalyst are highly specific but it's aim is just to faster the reaction not to rupture at high temperature or to synthesise the material.
So, False
6. True
In physical adsorption there is no bond formation between adsorbate and adsorbent. So, the energy required is very low. Hence equilibrium is attained rapid and reversible .
3. True.
Adsorption acts as catalyst . When the molecules are adsorbed then this adsorption lower the energy required to break the old bonds and thus new bond formation takes place easily and hence the product is formed.
Without adsorption it will take more energy to break the bonds.
