Total pressure for both systems is 14.26atm.

Explanation:

Kp for the reaction is:

As C is a pure solid, is not taken into account for Kp expression.

5.207g of H₂ are:

5.207g ₓ (1 mol / 2.01g) = 2.59moles of gas.

Using PV = nRT:

P = 2.59molₓ0.082atmL/molKₓ1000K / 9.32L = 22.8atm

The expressions for pressure in equilibrium are:

P{H₂} = 22.8atm - 2X

P{CH₄} = X

Replacing in Kp expression:

0.263 = X / (22.8 - 2X)²

0.263 = X / 520 - 91.2X +4X²

136.8 - 24X + 1.052X² = X

Solving for X:

X = 8.54atm → Right solution

X = 15.22atm → False solution. Because produce a negative concentration.

Replacing:

P{H₂} = 22.8atm - 2*8.54atm = 5.72atm

P{CH₄} = 8.54atm

Pressure of H₂ is 5.72atm and pressure of CH₄ is 8.54atm. Total pressure is:

5.72atm + 8.54atm = 14.26atm

As mass of Carbon is not taken into account is Kp expression and mass of hydrogen is the same with the same volume, total pressure is also 14.26atm

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
