Questions & Step-by-Step Solutions

Which of the following statements is true regarding adsorption?
Correct Answer: Adsorption is generally an exothermic process, as it releases energy.
  • Step 1: Understand what adsorption means. Adsorption is the process where molecules stick to the surface of a solid or liquid.
  • Step 2: Learn about exothermic processes. An exothermic process is one that releases energy, usually in the form of heat.
  • Step 3: Recognize that during adsorption, when molecules adhere to a surface, energy is released.
  • Step 4: Conclude that since adsorption releases energy, it is considered an exothermic process.
