Given 1.115 atm of carbon monoxide reactimg with 1.553 atm of oxygen in a closed container at a constant temperatue, what is the theoretic yield of the carbon dioxide?

1. Write the equation and balance it.

2. I would convert CO and O2 to moles using PV = nRT
3a. Using the coefficients in the balanced equation, convert moles CO to moles CO2.
3b. Same procedure, convert moles O2 to moles CO2.
3c. It is likely you will have two different answers for 3a and 3b. obviously one of them must be wrong. The correct one is ALWAYS the smaller value.
4. Convert moles of CO2 from 3c to grams. grams = moles x molar mass. If you want it in pressure units, you can use PV = nRT.

To find the theoretical yield of carbon dioxide, we need to determine the stoichiometry of the reaction and use the given pressures of carbon monoxide and oxygen.

The balanced chemical equation for the reaction between carbon monoxide (CO) and oxygen (O2) to form carbon dioxide (CO2) is:

2CO + O2 → 2CO2

From the balanced equation, we can see that 2 moles of carbon monoxide react with 1 mole of oxygen to produce 2 moles of carbon dioxide.

First, we need to convert the given pressures from units of atm to units of moles using the Ideal Gas Law:

PV = nRT

Where:
P = pressure (in atm)
V = volume (in liters)
n = number of moles
R = gas constant (0.0821 L.atm/mol.K)
T = temperature (in Kelvin)

Since the problem states that the temperature is constant, we can ignore it for now.

Let's calculate the number of moles of carbon monoxide (CO) using the given pressure:

n1 = (P1 * V1) / R

Where:
P1 = pressure of CO
V1 = volume of CO (unknown in this case, assuming constant)
R = gas constant

Next, we calculate the number of moles of oxygen (O2) using its pressure:

n2 = (P2 * V2) / R

Where:
P2 = pressure of O2
V2 = volume of O2 (unknown in this case, assuming constant)
R = gas constant

Now, we can calculate the theoretical yield of carbon dioxide (CO2) using the stoichiometry of the balanced equation:

n_CO2 = (2 * min(n1, n2)) / 2

Since the coefficients of CO and O2 are both 1, we can choose the smaller number of moles between n1 and n2. Then we divide it by 2 to get the number of moles of CO2.

Finally, we can convert the number of moles of CO2 back to pressure using the Ideal Gas Law:

P_CO2 = (n_CO2 * R) / V3

Where:
P_CO2 = pressure of CO2 (theoretical yield)
n_CO2 = number of moles of CO2
R = gas constant
V3 = volume of the closed container (unknown in this case, assuming constant)

Make sure to substitute the appropriate values and units into the formulas to find the theoretical yield of carbon dioxide.
