Question
Chapter 17, Problem 17.45SP
Interpretation Introduction
Interpretation:
The exothermic reaction is spontaneous and endothermic reaction are non-spontaneous should be explained.
Concept Introduction:
- Spontaneous reaction: A process which can take place by itself without the help of an external activity under the given set condition is called a spontaneous process. The term spontaneity simply means the feasibility of a process and the spontaneous processes are called feasible processes.
- Non-spontaneous reaction: A process in which one has no tendency to occur or which is forbidden and is made to occur only if external energy is continuously supplied.
- Exothermic reaction: The reaction which releases energy in the form of heat
- Endothermic reaction: The reaction in which heat energy is absorbed from the surrounding.
- Enthalpy (ΔH):- It is defined as the sum of internal energy and the pressure-volume energy of the system.
ΔH=ΔU+PΔV - Entropy (ΔS):-It is defined as a measure of the disorder or randomness of the system. More the randomness , more is the entropy.
ΔS=qΔT - Gibb’s free energy (ΔG):- It is the amount of energy available from a system that can be converted into useful work. It is a measure of its capacity to do useful work.
ΔG=ΔH−TΔS
To explain:
The exothermic reaction are spontaneous and endothermic reactions are non-spontaneous.
