Answer: X2Y3
Explanation: I had the same question ;) (and got it right)
Answer:
103.6°C
Explanation:
We solve this problem, with the Ideal Gases Law. We know that moles of gas are not changed through time.
P . V = n . R . T
So n (number of moles) and R (Ideal Gases constant) are the same, they are cancelled. In the two different states, we can propose:
P₁ . V₁ / T₁ = P₂ . V₂ /T₂
We need to make some conversions:
100 mL . 1 L/ 1000mL = 0.1L
500 kpa . 1atm / 101.3 kPa = 4.93 atm
300°C + 273 = 573 K
We replace data:
4.93 atm . 10L / T₂ = 750 atm . 0.1L / 573K
4.93 atm . 10L = (750 atm . 0.1L / 573K) . T₂
(4.93 atm . 10L) / (750 atm . 0.1L / 573K) → T₂
T₂ = 376.65 K
We convert K to °C → 376.65 K - 273 = 103.6 °C
Answer:
d. spontaneous in the reverse direction at all temperatures.
Um an answer lol sorry I don't know
