non spontaneous process happen in the universe but energy has to be provided to them . the free energy change of such processes are positive . the amount of temperature has to be increased to carry out such reactions
Non-spontaneous processes can occur in the universe, but they typically require an input of energy or outside influence to drive them. While spontaneous processes tend to occur without intervention, non-spontaneous processes may still happen with the appropriate energy input or conditions. Examples include charging a battery or separating water into hydrogen and oxygen through electrolysis.
During physical or chemical processes, energy can change from one form to another but is never created or destroyed, in accordance with the law of conservation of energy. Energy can be converted between kinetic energy, potential energy, thermal energy, etc., without the total energy of the universe changing. This means that the total energy of the universe remains constant over time.
It tells if the reaction will process spontaneously or not
it can never be spontanious
Spontaneous combustion of paper typically occurs at temperatures higher than 230 degrees Celsius, not 34.5Ā°C, so the paper is unlikely to undergo spontaneous combustion at this temperature.
No, many exothermic reactions need the heat of activation to start the reaction. Paper, for instance, does not spontaneously burst into flame... you need to raise its temperature to the kindling point for it to burn.

Radioactivity, and more specifically, radioactive decay, involves the spontaneous expulsion of a proton from the nucleus of an atom. It is important to note that this process is random and spontaneous; in other words, we can never know exactly when an element will decay.
Everying in the universe is made up of atoms. If atoms didnt agsist, then life would act as if you were never born.
universe never ends
The spontaneity of a reaction is determined by the sign of the Gibbs free energy (ĪG). If both enthalpy (H) and entropy (S) are positive, the reaction can be spontaneous at high temperatures where the TĪS term outweighs the positive ĪH term, resulting in a negative ĪG. This means the reaction will be spontaneous at elevated temperatures.
never never never
The reaction is exothermic
Well, the universe never stops so... the universe does not have a center.
Portugal has never won a Miss Universe title.
By definition, beside and never intersecting our universe. ;)
Afghanistan has never won Miss Universe.
The universe is so big and it will never be completely populated because it includes areas that are unlivable. The Earth is part of the whole universe.
