SUMMARY
The kinetic energy (KE) of carbon monoxide (CO), carbon dioxide (CO2), and sulfur trioxide (SO3) at 276 K can be calculated using the equation KE = (3/2) RT, where R is the ideal gas constant (8.314 J/mol-K). However, this equation is applicable primarily to monatomic ideal gases. For polyatomic molecules like CO, CO2, and SO3, it is essential to consider the degrees of freedom to accurately compute their kinetic energy. The discussion highlights the incorrect application of the KE formula for CO and emphasizes the need for a more nuanced approach for polyatomic gases.
