A 1 kg ideal gas mixture at 1 atm has the following mass composition: 15% O2, 50% N2, 35% CO2. Calculate using tabulated enthalpies only, the amount of energy (in kJ) required to raise the temperature of the gas mixture from 100 °C to 200 °C (at constant pressure).
It should shift to the right because the removal of a component causes the equilibrium to shift to the side from which the component was removed.
At equilibrium the total pressure and density of the gaseous mixture were 1.80atm and 1.60g L-1, respectively. Calculate Kc and Kp.
