Question

The translational kinetic energy of the molecules of \(22\) grams of \(CO_2\) at \(27^\circ C\) is \[ (R=8.314\ \text{J mol}^{-1}\text{K}^{-1}) \]

• A. \(1870.6\ \text{J}\)
• B. \(164.7\ \text{J}\)
• C. \(2000\ \text{J}\)
• D. \(2200\ \text{J}\)

Hint:

For any ideal gas, \[ \text{Total Translational K.E.} = \frac32 nRT. \] It depends only on the number of moles and absolute temperature, not on the nature of the gas.

Answer 1

The Correct Option is A
