Chemical Reaction Engineering MCQ on Packed Bed Catalytic Reactor

True False Chemisorption increases with increase in pressure Chemisorption decreases with increase in pressure Chemisorption increases with decrease in pressure Change of pressure has no effect on Chemisorption Energy of adsorption of gas molecules to the adsorbent site is different at different adsorbing site Maximum amount of adsorption corresponds to a monolayer Desorption rate depends on the amount of material adsorbed onto the solid surface Gas phase molecules are adsorbed on discrete points on the solid surface Proportional to the square of the partial pressure of the gas Proportional to the partial pressure of the gas Inversely proportional to the square of the partial pressure of the gas Inversely proportional to the partial pressure of the gas Diffusion → Adsorption → Reaction → Desorption → Diffusion → Mass transfer → Mass transfer Mass transfer → Diffusion → Adsorption → Reaction → Desorption → Diffusion → Mass transfer Mass transfer → Diffusion → Adsorption → Desorption → Diffusion → Mass transfer → Reaction Mass transfer → Adsorption → Diffusion Reaction → Desorption → Diffusion → Mass transfer Rate of adsorption > Rate of desorption Rate of adsorption < Rate of desorption Rate of adsorption = Rate of desorption Rate of adsorption ≠ Rate of desorption
