Because rusting is a spontaneous process under standard conditions, which of the following is a correct conclusion about the process?
OA "Delta G' is positive and 'DeltaH' is greater than the product of temperature and Deltas
OB. "Delta' is positive and the product of temperature and Deltas' is greater than 'DeltaH'.
O c.
Deltag'is negative and the product of temperature and Deltas" is greater than "Delta".
Delta G' is negative and 'DeltaH' is greater than the product of temperature and Deltas.

The correct conclusion about the process is that "DeltaG" is negative and the product of temperature and "DeltaS" is greater than "DeltaH". That is option C

Spontaneous reaction are natural reactions that occurs without depending on energy from external sources.

A typical example of a spontaneous reaction is the rusting of iron.

To know if a reaction is spontaneous, second law of thermodynamics is used through Gibbs free energy.

At standard conditions ( constant temperature and pressure), Gibbs free energy(G) is equal to enthalpy change(ΔH) minus product of temperature(T) and the entropy change (ΔS) of the system.

That is, ΔG =ΔH −TΔS,

Entropy (S) is a measure of the degree of disorderliness of a system.

Enthalpy (H) is the heat of the reaction which is positive when heat is given out or negative when heat is absorbed.

From the formula, when ∆G is less than 0, the reaction is said to be spontaneous.

For ∆G to be less than 0, this means ∆H(DeltaH) is less than 0 and T∆ S( product of temperature and "DeltaS") is greater than 0 to achieve a negative value for ∆G(DeltaG)

Therefore, DeltaG" is negative and the product of temperature and "DeltaS" is greater than "DeltaH".

A spontaneous reaction is known by the fact that ΔG is negative and the product of temperature and ΔS is greater than ΔH.

Spontaneity in chemical reactions

A chemical reaction is said to be spontaneous when it can proceed on its own without any further input of energy. Recall that;

ΔG = ΔH - TΔS

Where;

  • ΔG = change in free energy
  • ΔH = change in enthalpy
  • T = temperature
  • ΔS = change in entropy

Hence, a reaction is spontaneous when ΔG is negative and the product of temperature and ΔS is greater than ΔH.
