Spontaneous processes tend to increase the stability of a system by moving it towards a lower energy state or higher entropy state, which are more stable configurations. This is in line with the second law of thermodynamics, which states that systems tend towards higher disorder and lower energy to increase stability.
What else can I help you with?
Is adsorption spontaneous?
Yes, adsorption is typically a spontaneous process because it involves the attraction of molecules to a surface due to the energetically favorable interactions between them. This can result in a decrease in free energy and an increase in the stability of the system.
Which o the following would most likely be spontaneous?
To determine which process would be most likely spontaneous, we typically consider factors like changes in enthalpy and entropy. A process that results in a decrease in enthalpy (exothermic) and an increase in entropy (disorder) is generally spontaneous. For example, the melting of ice at room temperature is spontaneous because it absorbs heat (endothermic) but results in a significant increase in entropy. Without specific options provided, it's essential to assess these thermodynamic principles to identify spontaneous processes.
Why the stability decrease with increasing atomic mass?
Stability depends on to proton/neutron ratio; and this ratio increase with the atomic number.
What does spontaneous changes always increase?
Spontaneous changes always increase the entropy of a system and its surroundings, according to the second law of thermodynamics. Entropy is a measure of the disorder or randomness of a system, and spontaneous processes tend to move toward more disordered states. This increase in entropy reflects a natural tendency for systems to evolve toward equilibrium, where energy is more evenly distributed.
What is the spontaneous increase in disorder or entropy?
The spontaneous increase in disorder or entropy refers to the natural tendency of systems to evolve from ordered states to more disordered ones over time. This concept, rooted in the second law of thermodynamics, suggests that in an isolated system, the total entropy will either increase or remain constant; it will never decrease. Entropy can be thought of as a measure of the number of possible arrangements of the components of a system, with higher entropy indicating more disorder. This phenomenon is observed in various processes, such as the mixing of gases or the melting of ice.
Does the entropy of the surroundings increase for spontaneous processes?
Yes, the entropy of the surroundings increases for spontaneous processes.
Is adsorption spontaneous?
Yes, adsorption is typically a spontaneous process because it involves the attraction of molecules to a surface due to the energetically favorable interactions between them. This can result in a decrease in free energy and an increase in the stability of the system.
What is in the middle of decrease and increase?
The midpoint between decrease and increase is stability or equilibrium, where there is neither a decrease nor an increase occurring.
Why are all spontaneous processes irreversible?
Spontaneous processes are irreversible because they involve an increase in entropy, or disorder, in the system. This increase in entropy leads to a loss of energy that cannot be fully recovered, making the process irreversible.
What conditions must be met for a spontaneous process to occur?
For a spontaneous process to occur, the conditions must involve an increase in entropy and a decrease in free energy.
Which o the following would most likely be spontaneous?
To determine which process would be most likely spontaneous, we typically consider factors like changes in enthalpy and entropy. A process that results in a decrease in enthalpy (exothermic) and an increase in entropy (disorder) is generally spontaneous.

Without specific options provided, it's essential to assess these thermodynamic principles to identify spontaneous processes.
Why does the entropy of the universe increase for spontaneous processes?
The entropy of the universe increases for spontaneous processes because the second law of thermodynamics states that in any spontaneous process, the overall entropy of a closed system will always increase over time. This is because the natural tendency of systems is to move towards a state of higher disorder and randomness, leading to an increase in entropy.
Why the stability decrease with increasing atomic mass?
Stability depends on to proton/neutron ratio; and this ratio increase with the atomic number.
How do you know if a reaction is spontanious?
A reaction is spontaneous if it occurs without any external intervention and leads to a decrease in Gibbs free energy. This is driven by the system's tendency to increase entropy and decrease in internal energy. Mathematically, a reaction is spontaneous if ΔG < 0 at constant temperature and pressure.
What does spontaneous changes always increase?
Spontaneous changes always increase the entropy of a system and its surroundings, according to the second law of thermodynamics.

Is an increase in entropy of a system sufficient to make a process spontaneous?
Yes, an increase in entropy of a system is sufficient to make a process spontaneous.
