How is the P-v-T behavior of a component in an ideal-gas mixture expressed? How is the P-v-T behavior of a component in a real-gas mixture expressed? Multiple Choice The P-v-T behavior of a component in an ideal-gas mixture is expressed by the ideal-gas equation of state using the properties of the mixture instead of the individual components, Pivi = RiTi. The P-v-T behavior of a component in a real-gas mixture is expressed by more complex equations of state, or by PiVi = ZiRiTi, where Zi is the compressibility factor.
