The root mean square speed of hydrogen molecules at a
P certain temperature is \( 300 \mathrm{~m} / \mathrm{s} \). If the temperature is doubled
\( \mathrm{DV} \) and hydrogen gas dissociates into atomic hydrogen, the rms speed will become:
a. \( 424.26 \mathrm{~m} / \mathrm{s} \)
b. \( 300 \mathrm{~m} / \mathrm{s} \)
c. \( 600 \mathrm{~m} / \mathrm{s} \)
d. \( 150 \mathrm{~m} / \mathrm{s} \)
