A flask contains argon and chlorine in the ratio of \(2: 1\) by mass. The temperature of the mixture is \(27^{\circ} \mathrm{C}\). The ratio of average kinetic energies of two gases per molecule is
- A \(1:1\)
- B \(2:1\)
- C \(3:1\)
- D \(6:1\)
Answer & Solution
Correct Answer
(A) \(1:1\)
Step-by-step Solution
Detailed explanation
(a) The average kinetic energy of molecules is given by \(\mathrm{KE}_{\mathrm{av}}=\frac{3}{2} K T\). So it depends only on temperature \(\mathrm{KE}_1: \mathrm{KE}_2=1: 1\)
