What is the heat of adsorption, and how is it related to residual forces?
Options
- AIt increases residual forces.
- BIt has no effect on residual forces.
- CIt decreases residual forces.
- DIt stabilizes residual forces.
Correct answer
C. It decreases residual forces.
Step-by-step solution
The paragraph states that during adsorption, there is always a decrease in residual forces of the surface, i.e., a decrease in surface energy, which appears as heat.
