Steam reforming of methane ( CH4 ) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the sta

Hatshy [7]

<u>Answer:</u> The pressure equilibrium constant for the reaction is 1473.8

<u>Explanation:</u>

We are given:

Initial partial pressure of methane gas = 2.4 atm

Initial partial pressure of water vapor = 3.9 atm

Equilibrium partial pressure of hydrogen gas = 6.5 atm

The chemical equation for the reaction of methane gas and water vapor follows:

$CH_4+H_2O\rightleftharpoons CO+3H_2$

<u>Initial:</u> 2.4 3.9

<u>At eqllm:</u> 2.4-x 3.9-x x 3x

Evaluating the value of 'x':

$\Rightarrow 3x=6.5\\\\x=2.167$

So, equilibrium partial pressure of methane gas = (2.4 - x) = [2.4 - 2.167] = 0.233 atm

Equilibrium partial pressure of water vapor = (3.9 - x) = [3.9 - 2.167] = 1.733 atm

Equilibrium partial pressure of carbon monoxide gas = x = 2.167 atm

The expression of $K_p$ for above equation follows:

$K_p=\frac{p_{CO}\times (p_{H_2})^3}{p_{CH_4}\times p_{H_2O}}$

Putting values in above equation, we get:

$K_p=\frac{2.167\times (6.5)^3}{0.233\times 1.733}\\\\K_p=1473.8$

Hence, the pressure equilibrium constant for the reaction is 1473.8

Please help me, It's my last question :)

Vedmedyk [2.9K]

<h3>Given:</h3>

$V_{1} = \text{5 L}$

$T_{1} = \text{298 K}$

$V_{2} = \text{3 L}$

<h3>Unknown:</h3>

$T_{2}$

<h3>Solution:</h3>

$\dfrac{V_{1}}{T_{1}} = \dfrac{V_{2}}{T_{2}}$

$T_{2} = T_{1} \times \dfrac{V_{2}}{V_{1}}$

$T_{2} = \text{298 K} \times \dfrac{\text{3 L}}{\text{5 L}}$

$\boxed{T_{2} = \text{179 K}}$
