A sample of fluorine has a volume of 1.79 L when the temperature is 101.5 deg C and the pressure is 794 torr. Explain what will be the volume when the pressure is 73.02 kPa as well as the temperature is 223.2 deg C?
Determine the value of K (the thermodynamic equilibrium constant) at each temperature. b) Assuming that ?H°rxn is independent of temperature, determine the value of ?H°rxn from these data.
