Explanation: Calculate D1m from the equation, D1m=(1-Y1)/(∑〖Yj/Dij〗)
D1m=0.465cm2/s
Use the equation, N1=(D1mC/l)*ln〖(1-Yil)/(1-Y10)〗, where Yil=0(dry air) and Y10=0.023 (17.53/760).

°C. Assuming ideal gas behavior, what is the partial pressure of hydrogen in the mixture?
To determine the partial pressure of hydrogen, we first need to calculate the total pressure of the mixture. Since the total pressure is given as 1 atm, we can use this information to find the partial pressure of hydrogen.
To find the partial pressure of hydrogen, we need to calculate the mole fraction of hydrogen in the mixture. The mole fraction is calculated by dividing the number of moles of hydrogen by the total number of moles in the mixture.
Let's assume we have 100 moles of the mixture. Since the mixture is 60% hydrogen and 40% oxygen, we have 60 moles of hydrogen and 40 moles of oxygen.
The mole fraction of hydrogen is therefore:
Mole fraction of hydrogen = Number of moles of hydrogen / Total number of moles in the mixture
= 60 / 100
= 0.6
Now that we have the mole fraction of hydrogen, we can calculate the partial pressure of hydrogen using Dalton's Law of Partial Pressures. According to Dalton's Law, the partial pressure of a gas in a mixture is equal to the mole fraction of that gas multiplied by the total pressure of the mixture.
Partial pressure of hydrogen = Mole fraction of hydrogen * Total pressure of the mixture
= 0.6 * 1 atm
= 0.6 atm
Therefore, the partial pressure of hydrogen in the mixture is 0.6 atm.

Partial pressure of hydrogen = Mole fraction of hydrogen * Total pressure of the mixture
= 0.6 * 1 atm
= 0.6 atm
Therefore, the partial pressure of hydrogen in the mixture is 0.6 atm.
