Which of the following statement about Avogadro's hypothesis is correct?
Which of the following statement about Avogadro's hypothesis is correct?
- A. Under similar conditions of temperature and pressure, gases react with each other in simple ratio.
- B. Under similar conditions of temperature and pressure, equal volumes of all gases contain same number of molecules
- C. At NTP all gases contain same number of molecules
- D. Gases always react with gases only at the given temperature and pressure
Step-by-step solution
Avogadro's hypothesis states that at the same temperature and pressure, equal volumes of all gases contain an equal number of molecules. This is a fundamental law of chemical combination. Option A describes Gay-Lussac's law of combining volumes, option C is imprecise because it doesn't specify equal volumes, and option D is false.
