Which of the following factors affects the rate of chemisorption?
Temperature
Pressure
Surface area of the adsorbent
All of the above
The rate of chemisorption is affected by various factors like temperature, pressure, and surface area of the adsorbent. An increase in temperature or pressure usually leads to an increase in the rate of chemisorption. A larger surface area of the adsorbent provides more sites for chemisorption to occur, resulting in a higher rate of chemisorption.
