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.

What happens to the energy of the universe during physical or chemical process?
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.
How does the Gibbs free energy predict spontaneity?
It tells if the reaction will process spontaneously or not
What can be said about a reaction with H 620 kJmol and S -0.46 kJ molK?
it can never be spontanious
How many hours will it take for a paper to undergo spontaneous combustion under 34.5 degrees celsius?
Spontaneous combustion of paper typically occurs at temperatures higher than 230 degrees Celsius, not 34.5°C, so the paper is unlikely to undergo spontaneous combustion at this temperature.
Are endothermic reactions always nonspontaneous?
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.
What must happen to the entropy of the universe during a spontaneous reaction or process?
The entropy of the universe must increase during a spontaneous reaction or process. This is in accordance with the Second Law of Thermodynamics, which states that the total entropy of an isolated system can never decrease over time.

How is the radioactive decay of an element used to determine the age of a rock layers?
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.
What is the biggest in the universe?
universe never ends
What happens if there was no atom?
Everying in the universe is made up of atoms. If atoms didnt agsist, then life would act as if you were never born.
When will the cyclops take over the universe?
never never never
What kind of reaction occurs when the entropy change of an endothermic reaction is negative?
The reaction is exothermic
How many miles to the center of the universe?
Well, the universe never stops so... the universe does not have a center.
What country never won Miss Universe before?
Portugal has never won a Miss Universe title.
Who is Miss Universe of Afghanistan?
Afghanistan has never won Miss Universe.
Where can you find a parallel universe?
By definition, beside and never intersecting our universe. ;)
Why is the universe so big - you will never populate it?
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.
