Answer : The average kinetic energy per molecule is, [tex]6.6861\times 10^{-21}J[/tex]
Explanation :
The formula for average kinetic energy per molecule is:
[tex]K.E=\frac{3}{2}kT[/tex]
where,
k = Boltzmann’s constant = [tex]1.38\times 10^{-23}J/K[/tex]
T = temperature = [tex]50^oC=273+50=323K[/tex]
Now put all the given values in the above average kinetic energy formula, we get:
[tex]K.E=\frac{3}{2}\times (1.38\times 10^{-23}J/K)\times (323K)[/tex]
[tex]K.E=6.6861\times 10^{-21}J[/tex]
Therefore, the average kinetic energy per molecule is, [tex]6.6861\times 10^{-21}J[/tex]
