Question $1(1$ point$)$

In a Maxwell$-$Boltzmann distribution experiment conducted at $273\mathrm{.}15K,$ you find that the maximum peak of the distribution occurs for a molecular speed of $450m{s}^{-1}.$ Which of the following statements is true?

a$)$ The most probable speed $(u_m)$ is greater than $450m{s}^{-1}$

b$)$ The root mean square velocity $(u_{rms})$ of the molecules is $450m{s}^{-1}$

c$)$ The average speed $(u_{av})$ of the molecules is greater than $450m{s}^{-1}$

d$)$ No molecules have a speed greater than $450m{s}^{-1}$

e$)$ The average speed $(u_{av})$ of the molecules is less than $450m{s}^{-1}$
