Answer:
1.59 atm
Explanation:
The reaction is:
The dalton's law tell us that the total pressure of a mixture of gases is the sum of the partial pressure of every gas.
So after the reaction the total pressure is:
we don't include because it decomposed completely.
Assuming ideal gases
PV=nRT
P= pressure, V= volume of the container, n= mol of gas, R=constant of gases and T=temperature.
so moles of is:
from the reaction stoichiometry (1:1) we have that after the reaction the number of moles of each product is the same number of moles of .
The partial pressure of each gas is:
so total pressure is:
replacing the moles we get:
We know that T2=3*T1
replacing this value in the equation we get:
Answer:
1.57 mol NaN₃
Explanation:
- 2 NaN₃ (s) → 2 Na (s) + 3 N₂ (g)
First we <u>use PV=nRT to calculate the number of N₂ moles that need to be produced</u>:
- P = 1.07 atm
- V = 53.4 L
- n = ?
- R = 0.082 atm·L·mol⁻¹·K⁻¹
- T = 23.7 °C ⇒ 23.7 + 273.16 = 296.86 K
<u>Inputing the data</u>:
- 1.07 atm * 53.4 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 296.86
And <u>solving for n</u>:
- n = 2.35 mol N₂
Finally we <u>convert N₂ moles into NaN₃ moles</u>, using <em>the stoichiometric coefficients of the balanced reaction</em>:
- 2.35 mol N₂ *
= 1.57 mol NaN₃
