<h3>
Answer:</h3>
- Balanced Equation; 2Fe + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂
- Why balance?: To obey the law of conservation of mass
- Subscripts can not be changed, since they show the actual number of atoms of each element in a compound.
<h3>
Explanation:</h3>
- The balanced equation for the reaction between the iron metal and sulfuric acid to produces iron (III) sulfate and hydrogen gas is given by;
2Fe + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂
- Balancing chemical equations ensures that they obey the law of conservation of mass which requires the mass of reactants and the mass of products to be equal.
- Balancing is done by putting coefficients on reactants and products while not affecting the subscripts as subscripts show the actual number of atoms of an element in a compound.
Answer:
ΔG° = - RTLnK is used to find the standard cell potential given the equilibrium constant
Explanation:
for an ideal disolution:
⇒ ΔG = RT∑ni LnXi
∴ ΔG = ( μi - μi*)ni
∴ μ : chemical potential
∴ μ*: chem. potential of the pure component at T and P.
⇒ ΔG = μi - μi* = RT LnXi
for a equilibrium reaction:
⇒ ∑ νi*μi = 0
⇒ ΔGr = ΔG°+ RT Ln Kx = 0
⇒ ΔG° = - RT LnKx
