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.
