What caused agriculture to change in Britain leading to urbanization? Check all that apply.
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:
2 KNO₃ + 10 K → 5 K₂O + N₂ (option 1)
Explanation:
1. 2 KNO₃ + 10 K → 5 K₂O + N₂
We have in reactant side:
2 K, 2N, 6O and 10 K. In conclussion, 12 K, 2N and 6 O
We have in product side.
10 K, 5O and 2 N
This equation is unbalanced
2. 2 SO₂ + O₂ → 2 SO₃
In reactant side we have 2 S and 6 O
In product side we have 2 S and 6 O
3. SF₄ + 3 H₂O → H₂SO₃ + 4 HF
In reactant side we have 1 S, 4F, 6 H and 3 O
In product side we have 1 S, 4F, 6 H and 3 O
Lead (IV) nitrate + sodium sulfate lead(IV) sulfate + sodium nitrate
