Question
Chapter 17, Problem 40P
Interpretation Introduction
Interpretation: To identify the stimulant in Coffee, tea and cola drinks.
Concept introduction: Stimulants are types of drugs which increase the activity of the central nervous system (CNS) and the body; these drugs are pleasurable and invigorating, and may have sympathomimetic effects. The stimulants are extensively used throughout the world as prescription drugs plus illicitly as performance-enhancer or for recreational activities. The most often prescribed stimulants were methylphenidate, lisdexamfetamine, amphetamine etc.
Correct answer: Option (b) is the correct answer; Caffeine (b)

and show that with 2V lattice sites on each side of the permeable barrier and a total of 2V white
particles and 2V black particles, that perfect de-mixing (all one color on each side of the barrier)
becomes increasingly unlikely as V increases.
