Higher energy is required to make the reaction occurring in the system spontaneous. An increase in entropy ensures that the reaction is spontaneous in nature. Systems at a higher temperature, where molecules move faster on average, have a greater number of possible microstates for how the kinetic energy is distributed, so entropy increases with temperature.
When one asks a ``why?" question, it’s important that the assumptions ware spelled out.
Entropy is a measure of the possible states a system can be found in-under certain constraints. So ``high entropy" means a system has more states at its disposal than ``low entropy". So it’s more likely to be found among the states consistent with the former than with the latter.
Temperature is a measure of the kinetic energy of a system. So high temperature means the system can move more easily than at low temperature, so there are many more ways it can be found in a state consistent with the value of the temperature, the higher the temperature; which means that, typically, the higher the temperature, the higher the entropy.
All this is the material of courses in thermodynamics.
Systems at a higher temperature, where molecules move faster on average, have a greater number of possible microstates for how the kinetic energy is distributed, so entropy increases with temperature. Entropy increases as temperature increases. An increase in temperature means that the particles of the substance have greater kinetic energy. The faster-moving particles have more disorder than particles that are moving slowly at a lower temperature. Entropy is a measure of disorder; when systems become more disordered, the change in entropy is positive. When change entropy is positive, it makes the change more spontaneous. Changes in temperature will lead to changes in entropy. The higher the temperature the more thermal energy the system has; the more thermal energy the system has, the more ways there are to distribute that energy; the more ways there are to distribute that energy, the higher the entropy. When the situation is indeterminate, a low temperature favors the (entropy/ enthalpy factor, and a high temperature favors the entropy enthalpy) factor. Is the reaction in Problem 9 spontaneous? NO OG = (+) → not spent what is the value of AG if AH = +12.0 KJ, AS = -5.00 kJ/K and T = 290. With decrease in temperature, randomness (entropy) decreases because the motion of particles decreases and their velocity decreases so they have less entropy at a lower temperature. Lower energy is preferred because it will make the system more stable in nature. Higher energy is required to make the reaction occurring in the system spontaneous. An increase in entropy ensures that the reaction is spontaneous in nature. Nature's bias is towards an increase in entropy. This is a fundamental law of the universe; there is no reason that can be used to explain why nature prefers high entropy to low entropy. Instead, increasing entropy is itself the basic reason for a wide range of things that happen in the universe.
