The vapor pressure of water and the partial pressure of hydrogen contribute to the total pressure of 715 torr. What is the parti

Lostsunrise [7]

Answer:

0.91 atm is the partial pressure of just hydrogen gas.

Explanation:

Vapor pressure of water , p= 0.0313 atm

Partial pressure of hydrogen gas = $p_{H_2}$

Total pressure of the water vapors and hydrogen gas = P = 715 Torr

1 atm = 715 Torr

$715 Torr=\frac{715}{760} atm=0.94 atm$

According Dalton's law of partial pressure:

$P=p+p_{H_2}$

$0.94 atm=0.0313 atm+p_{H_2}$

$p_{H_2}=0.94 atm - 0.0313 atm =0.9087 atm \approx 0.91 atm$

0.91 atm is the partial pressure of just hydrogen gas.

2. In the reaction NO + NO2 ⇌ N2O3, an experiment finds equilibrium concentrations of [NO] = 3.8 M, [NO2] = 3.9 M, and [N2O3] =

notsponge [240]

Kc= concentration of product divided by concentration of reactant
NO + NO2 ----> N2O3

Kc =(N2O3) / (No)(NO2)

Kc= ( 1.3 )/{ (3.9)(3.8) }

Kc=0.088 ( answer B)
