The temperature of the carbon dioxide atmosphere near the surface of venus is 475°c. calculate the average kinetic energy per mole of carbon dioxide molecules on venus. 2520 j/mol 5920 j/mol 4150 j/mol 5920 kj/mol 9330 j/mol

 9330 j/mol

The temperature of the gas is 475 ° Celcius which is equal to: 475 +273= 748 °K. The formula for kinetic energy of individual atoms would be

K= 3/2 * kB * T
If kB is 1.38 * 10^-23 J/K and 1 mol is made from 6.02*10^23 molecule, then the kinetic energy of 1 mol CO2 would be:
K= 3/2 * kB * T
K= 3/2 * 1.38 * 10^-23  * 748 * 6.02 *10^23 =9324 J/mol
