  1. A  \(6845.5 \mathrm{~J}\)
  2. B  \(5942.0 \mathrm{~J}\)
  3. C  \(6232.5 \mathrm{~J}\)
  4. D  \(5670.5 \mathrm{~J}\)
Verified Solution

Answer & Solution

Correct Answer

(C)  \(6232.5 \mathrm{~J}\)

Step-by-step Solution

Detailed explanation

\( \text { Kinetic energy }=\frac{f}{2} \mathrm{nRT} \) \( =\frac{5}{2} \times 1 \times 8.31 \times 300 \mathrm{~J} \) \( =6232.5 \mathrm{~J}\)
