How can I get the partial pressure value if I only know the concentration of the CO2?
For calculating the isotherm parameters, you can consider the breakthrough curve for the fixed bed column experiment by ploting the concentration of CO2 as a function of time. So, you can determine the adsorption capacity of the adsorbent material, the rate of adsorption, and the equilibrium constant too.
To determine the partial pressure of CO2, you need to know the total pressure and the mole fraction of CO2 in the gas mixture.The mole fraction of CO2 is the ratio of the number of moles of CO2 to the total number of moles of gas in the mixture. It can be calculated using the concentration of CO2 and the total pressure of the gas mixture, as follows:
mole fraction of CO2 = (concentration of CO2 / 100) * (total pressure / 1 atm)
Once you have determined the mole fraction of CO2, you can calculate the partial pressure of CO2 using the following formula:
partial pressure of CO2 = mole fraction of CO2 * total pressure
For example, if you have a gas mixture with a total pressure of 1 atm and a concentration of CO2 of 5%, you can calculate the mole fraction of CO2 as:
mole fraction of CO2 = (5 / 100) * (1 / 1) = 0.05
Then, you can calculate the partial pressure of CO2 as:
partial pressure of CO2 = 0.05 * 1 = 0.05 atm
Therefore, the partial pressure of CO2 in the gas mixture is 0.05 atm.
I hope this is helpful
