A sample of a gas has a volume of 852 mL at 298 K. If the gas is cooled to 200K, what would the new volume be?

Colt1911 [192]

Answer:

571.81 mL

Explanation:

Assuming constant pressure, we can solve this problem by using Charles' law, which states that at constant pressure:

V₁T₂=V₂T₁

Where in this case:

V₁ = 852 mL

T₂ = 200 K

V₂ = ?

T₁ = 298 K

We input the data:

852 mL * 200 K = V₂ * 298 K

And solve for V₂:

V₂ = 571.81 mL

The new volume would be 571.81 mL.

What is δg for the formation of solid uranium hexafluoride from uranium and fluorine at 25∘c when the partial pressure of f2 is

Sladkaya [172]

The reaction is

$U(s)+3F_{2} (g)-->UF_{6} (s)$

the Q of reaction will be

$Q = \frac{1}{(pF_{2})^{3}}$

$Q = \frac{1}{(0.054)^{3} } = 6350.66$

Δ $G=$ Δ $G^{0}+RTlnQ$

Putting values

ΔG = -2068000 + (8.314)(298)lnQ

ΔG = -2068000 + (8.314)(298)ln(6350.66) = -2046305 J /mol = -2046.3 kJ / mol
