Answer:
(A) The statement is false. The starting material is favored at equilibrium
Explanation:
As we know that type of reaction is predicted by value Gibbs free energy.
ΔG >0 It means that reaction is non spontaneous and favors the reactant of the reaction.
ΔG <0 It means that reaction is spontaneous and favors the product of the reaction.
As we know that
ΔG = ΔH -T ΔS
Here given that Assume the entropy term is small compared to the enthalpy term so ΔS = 0
⇒ ΔG = ΔH
Given that
ΔH o = 65 kJ/mol,
ΔG = ΔH = 65 kJ/mol
ΔG >0 It means that reaction is non spontaneous and favors the reactant of the reaction.
So the option A is correct.
(A) The statement is false. The starting material is favored at equilibrium.

Answer:
78.75g
Explanation:
The density of diamond is the mass of diamond per unit of its volume. The density of a substance is calculated using the formula:
Density (g/cm^3) = mass (g) / volume (cm^3)
According to the question, the density of diamond= 3.15g/cm^3, volume of diamond= 25cm^3, mass = ?
Hence, to calculate the mass, we say;
Mass = Volume × density
Mass = 25 × 3.15
Mass = 78.75
Therefore, the mass of diamond is 78.75grams.
Answer:
It's (6.02214179×1023) / one mole of substance.
