If DG for a reaction equals zero, the reaction
1 answer:
Answer: If for a reaction equals zero, the reaction is at equilibrium.
Explanation:
When a thermodynamic closed system tends to do the maximum amount of non-expansion work then the energy used to do this work is called Gibb's free energy.
The expression for can be written as follows.
where,
= enthalpy change
T = temperature
= entropy change
This means that is the difference between heat released in a process and the amount of heat released in a reversible manner for the same process. So, when the value of of
comes out to be equal to zero then it means no heat is released or absorbed.
Hence, the reaction is stable or at equilibrium.
Thus, we can conclude that the value of = 0 then it means that the reaction is at equilibrium.

Explanation:-
The balanced chemical solution is:
According to the neutralization law,
where,
= molarity of
solution = 0.117 M
= volume of
solution = 23.4 ml
= molarity of
solution = ?
= volume of
solution = 100.0 ml
= valency of
= 1
= valency of
= 1
Therefore, the concentration of ammonia in a solution will be 0.0274 M
