For carbon dioxide, the van der Waals constants are: a = 0.364 J∙m³/mol², and b = 4.27 × 10^-5 m³/mol. Assuming that the van der Waals equation holds at the critical point (where the p-V curve first becomes horizontal and has a point of inflection), what is the critical temperature of carbon dioxide?

The critical temperature (Tc) can be calculated using the van der Waals constants: Tc = (8a)/(27Rb), where R is the ideal gas constant (8.314 J/mol·K). Substituting the given values, Tc = (8 * 0.364) / (27 * 8.314 * 4.27 × 10^-5) ≈ 304 K.

For Carbon Dioxide, the Van Der Waals Constants Are: a =
