Is 2H2O2--2H2O O2 spontaneous?
The decomposition of hydrogen peroxide is spontaneous but some catalysts increase the speed of reaction.
On what conditions does a spontaneous reaction become spontaneous?
For some non-spontaneous reactions, you can change the temperature. For other non-spontaneous reactions, there is nothing you can do to make it spontaneous. Nature favors reactions that increase a system's entropy (disorder) and nature favors reactions that are exothermic (they release enthalpy). Any reaction that does both of these things is spontaneous at all temperatures. Any reaction that does neither of these things is never spontaneous. As far as this question is concerned, the interesting reactions are endothermic reactions that increase entropy and exothermic reactions that decrease entropy. Whether these reactions are spontaneous depends on the temperature. The first variety (endothermic, increase entropy) will be spontaneous at high temperatures; the second (exothermic, decrease entropy) will be spontaneous at low temperatures. To find the temperature at which a reaction becomes spontaneous, one may apply the Gibbs equation: DG = DH - TDS where capital Ds stand for the Greek capital delta.
Is evaporating rubbing alcohol spontaneous or non spontaneous?

Is candle burning a spontaneous or non spontaneous reaction?

Describe the changes in gas pressure?
The increase in solubility causes increase in pressure.

A chemical reaction has a positive H value and a positive S value Under what conditions is the reaction spontaneous?
the reaction is always spontaneous :) youre welcome =D i just took this on apex, the correct answer is the reaction is spontaneous only at high temperatures.

No.
How do you keep your man sexually involved with you?
Be spontaneous! Always treat them as if he/she were the mistress.
Do antibiotics increase the rate of spontaneous mutation?
no, it just kills you very slowly and very deadly
Are chemical reactions always spontaneous when H is negative and S is negative?
No, when H and S are both negative, the reaction will only be spontaneous below a certain temperature

Is laughter always spontaneous?
Laughter can be both spontaneous and intentional. Spontaneous laughter often occurs in response to something funny or amusing, while intentional laughter is purposely done for social reasons or to convey enjoyment.
How do you say spontaneity in a sentence?
Spontaneous is a word that would be replaced by "random" today. It means to be "fresh", "off the wall", and rather joyful. It can also mean "instantaneous." "Ellen and Elizabeth fell into a spontaneous conversation about boys." "Spontaneous combustion is always a danger with heat and petroleum products." "Jane has a knack for finding spontaneous fun."
