these are NOT the right answers. please answer onlt ifnyou know what you are doing, i will not hesitate to downvote if you get it wrong.

A gaseous mixture with a molar analysis of 20% CO2, 40% CO, and 40% O2 enters a heat exchanger and is heated at constant pressure. An equilibrium mixture of CO2, CO, and O2 exits at 3200 K, 1.5 bar. For the exiting mixture, determine the mole fractions of: (a) CO2 Yco, = i 0.21 (b) CO Yco = i 0.40 (c) O2 Yo = i 0.39
