Answer:
A. to cure human diseases
Explanation:
ΔG° for the reaction is 5.47kJ mol⁻¹.
The energy that a substance has available for utilization in a chemical reaction or transformation is known as the Gibbs free energy. Things frequently change into other things that have less Gibbs free energy. The Gibbs free energy change indicates whether a chemical reaction will take place spontaneously or not.
By using the formula;
ΔG° = −RTlnKp
Where,
R = 8.3Jk⁻¹mol⁻¹
T = Temperature = 427 + 273 = 700 K
Kp = 8×10⁻⁵(given)
Substituting the value, we get,
ΔG° = −8.3 × 700 × ln(23×10⁻⁵)
ΔG° = −8.3 × 700 × (ln(2³)+ln 10⁻⁵)
= - 8.3 × 700 × (ln(2³)+ln 10⁻⁵)
= − 8.3 × 700 × (2.07−11.5)
=5.47×10⁴Jmol¹
=5.47kJ mol⁻¹
Therefore, ΔG° for the reaction is 5.47kJ mol⁻¹.

Answer: 350torr
Explanation: it will reach such i high pressure level that it will reach contobey level
Answer:
kp= 3.1 x 10^(-2)
Explanation:
To solve this problem we have to write down the reaction and use the ICE table for pressures:
2SO2 + O2 ⇄ 2SO3
Initial 3.4 atm 1.3 atm 0 atm
Change -2x - x + 2x
Equilibrium 3.4 - 2x 1.3 -x 0.52 atm
In order to know the x value:
2x = 0.52
x=(0.52)/2= 0.26
2SO2 + O2 ⇄ 2SO3
Equilibrium 3.4 - 0.52 1.3 - 0.26 0.52 atm
Equilibrium 2.88 atm 1.04 atm 0.52 atm
with the partial pressure in the equilibrium, we can obtain Kp.
