Detailed Solution
i) The fraction of molecules with very low or very high speeds is very small. Mariman fraction of molecules have speed near to the most probable speed Vmpii) The fraction of molecules having speeds greater than minimum goes on increasing with increase in sped. It reaches to a maximum value and then begins to decrease.⇒A−Vmp ⇒B−Vav ⇒C−Vrms
