Question

On increasing the molecular mass of gaseous sample at constant temperature, the fraction of molecules having speed equal to most probable speed at that molecular mass

Answer: A

💡 Solution & Explanation

Peak height $f(u_{mp}) \propto \sqrt{M}$. At constant temperature, increasing mass makes the curve narrower and taller. Therefore, correct answer is A.
