(N/A) The Maxwell-Boltzmann distribution curve describes the distribution of speeds of molecules in a gas at a given temperature.
Key points of the Maxwell-Boltzmann distribution:
$1$. The fraction of molecules with very low or very high speeds is very small.
$2$. As the speed increases,the fraction of molecules possessing those speeds increases until it reaches a peak,after which it starts decreasing.
$3$. The peak of the curve represents the most probable speed,denoted as $u_{mp}$,which is the speed possessed by the maximum fraction of molecules.
$4$. The distribution depends on the temperature and the molar mass of the gas.
The graph plots the fraction of molecules $\left(\frac{\Delta N}{N}\right)$ on the y-axis against the molecular speed on the x-axis.
