Question $4$

Estimate the fraction of $O2$ molecules with speed in the range of $100\frac{m}{s}$ to $200\frac{m}{s}$ in a

gas at $500K?$

Question $5$

Calculate the fractions of molecules in a gas that have a speed in a range $K$ at the speed

$n{V}_{mp}$ relative to those in the same range at $v_{mp}$ itself. This calculation can be used to

estimate the fraction of very energetic molecules $($which is important for reactions$).$

Evaluate the ratio for $n=3$ and $n=4.$
