Answer:
Kc = 1.4752
Explanation:
- CH4 (g) + 2H2O (g) ↔ CO2 (g) + 4H2 (g)
⇒ Kc = ( [ CO2(g) ] * [ H2 ]∧4 ) / ( [ CH4 ] * [ H2O ]² )
∴ [ CO2 ] = ( 8.01 g * ( mol / 44.01 g ) ) / 1.5 L
⇒ [ CO2 ] = 0.1213 M
⇒ [ H2O ] = 0.877 mol / 1.5 L = 0.585 M
⇒ [ CH4 ] = 0.380 mol / 1.5 L = 0.253 M
⇒ [ H2 ] = (( 0.380 mol CH4 ) * ( 4 mol H2 / mol CH4 )) / 1.5 L = 1.013 M
⇒ Kc = (( 0.1213 ) * ( 1.013 )∧4 ) / (( 0.253 ) * ( 0.585 )² )
⇒ Kc = 1.4752
<u>Answer:</u> The solubility of nitrogen gas at 5.00 atm is
<u>Explanation:</u>
To calculate the molar solubility, we use the equation given by Henry's law, which is:
Or,
where,
are the initial concentration and partial pressure of nitrogen gas
are the final concentration and partial pressure of nitrogen gas
We are given:
Putting values in above equation, we get:
Hence, the solubility of nitrogen gas at 5.00 atm is
The electronegativity generally increases as you go from left to right across the periodic table. It decreases as you go down the periodic table. So the answer is nitrogen.
