Answer:
Explanation:
In this problem we only have information of the equilibrium, so we need to find a expression of the free energy in function of the constant of equilireium (Keq):
Being Keq:
![K_{eq}=\frac{[fructose][Pi]}{[Fructose-1-P]}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5Bfructose%5D%5BPi%5D%7D%7B%5BFructose-1-P%5D%7D)
Initial conditions:
![[Fructose-1-P]=0.2M](https://tex.z-dn.net/?f=%5BFructose-1-P%5D%3D0.2M)
![[Fructose]=0M](https://tex.z-dn.net/?f=%5BFructose%5D%3D0M)
![[Pi]=0M](https://tex.z-dn.net/?f=%5BPi%5D%3D0M)
Equilibrium conditions:
![[Fructose-1-P]=6.52*10^{-5}M](https://tex.z-dn.net/?f=%5BFructose-1-P%5D%3D6.52%2A10%5E%7B-5%7DM)
![[Fructose]=0.2M-6.52*10^{-5}M](https://tex.z-dn.net/?f=%5BFructose%5D%3D0.2M-6.52%2A10%5E%7B-5%7DM)
![[Pi]=0.2M-6.52*10^{-5}M](https://tex.z-dn.net/?f=%5BPi%5D%3D0.2M-6.52%2A10%5E%7B-5%7DM)
Free-energy for T=298K (standard):
Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the Sun.
Answer:
After 1.95x10⁴ s, total pressure is 0.34 atm
Explanation:
t(s) 0 1000 3000 7000
PTotal (atm) 0.15 0.16 0.18 0.20
These are the data of the experiment, so let's make a linear regression
X | Y
0 | 0.15
1x10³ | 0.16
3x10³ | 0.18
7x10³ | 0.20
You can do this by the calculator, but let's do it manually.
Y = mx + b
m = (Y₂ - Y₁) / (X₂ - X₁)
m = 0.18 - 0.16 / 3x10³ - 1x10³
m = 0.02 / 2x10³ = 1x10⁻⁵
b = 0.15 (y-intercept, where x is 09
Y = 1x10⁻⁵ X + 0.15
Notice that in the statement, after 7000 s, pressure is 0.22 atm
1x10⁻⁵ . 1.95x10⁴ + 0.15 = 0.34atm
