Spontaneous ...
Happens all by itself; typically unpredictable
Non-spontaneous...
You have to do something to make it happen.

∙ 11y agoA reaction in a fuel combustion cell is non spontaneous and irreversible. The heat (mostly by an electric spark) is given forcefully into the system.

Is the Uniform mixing of bromine vapor and nitrogen gas a spontaneous or non spontaneous reaction?
spontaneous
What is non reaction?
a non spontaneous reaction is a reaction that doesnt occur naturally and it normally tends to favor the reactants of a chemical reaction. Another thing is that it doesnt really produce free energy
What is the overall voltage for the non spontaneous redox reaction involving Mg and Cu and their irons?
-2.37 - 0.34
Is ice melting a spontaneous reaction?
Before we go into the details of whether melting of ice at a room temperature of 25 degree Celsius is spontaneous reaction or not, we first define the spontaneous and non-spontaneous reactions. Spontaneous Reaction, as you know, is a reaction that takes place on its own without an external force or other reaction to drive it e.g. rusting or iron nail, burning of wood etc. Non-Spontaneous Reaction is a reaction which cannot occur without the input of work from an external source. Such as charging of battery, as the electrons flow is required to charge it completely. Now replying to your question: First of all I think, though I am not sure, that heat doesn't transfer from ice to the room. Actually, heat transfers from room to the ice and that's how ice is caused to turn into liquid. The ice needs heat from the surrounding to have its molecules to jiggle (vibrate) and this shaking of ice molecules changes it into liquid. Remember, this reaction is physical, not chemical. From all I have studied and I know, I truly believe that the conversion of ice into liquid form is spontaneous reaction.
How can you reverse a redox reaction in a voltaic cell?
if the external circuit is replaced by a source of electricity that opposes the voltaic cell, the electrode reactions can be reversed.Now,the external source pushes the electrons in the opposite direction and supplies energy or work to the cell so that the reverse non-spontaneous reaction occurs.
Which best describes a galvanic cell a battery containing a non spontaneous reaction a battery containing an acid and a base a battery containing a spontaneous redox reaction a battery that requires?
spontaneous redox reaction
Is candle burning a spontaneous or non spontaneous reaction?
Spontaneous
Is the Uniform mixing of bromine vapor and nitrogen gas a spontaneous or non spontaneous reaction?
spontaneous
What is a non spontaneous reaction?
a non spontaneous reaction is a reaction that doesnt occur naturally and it normally tends to favor the reactants of a chemical reaction. Another thing is that it doesnt really produce free energy
What kind of cell has non spontaneous voltage?
Electrolytic cell
Forming a triacylglyceride from three fatty acids and glycerol...identify this reaction as either anabolic or catabolic endergonic or exergonic and spontaneous or non spontaneous.?
Anabolic, endergonic, non-spontaneous
How is an electrolytic cell different from a galvanic cell?
Electrons flow in the opposite direction.
Ask us anythingWhich of the following describes a nonspontaneous reaction?
a non spontaneous reaction is a reaction that doesnt occur naturally and it normally tends to favor the reactants of a chemical reaction. Another thing is that it doesnt really produce free energy
How do you determine whether a reaction is spontaneous or non spontaneous?
The first of two factors that determine whether a reaction is spontaneous or non-spontaneous is entropy. The second is energy. For a reaction to be spontaneous, it must have both of these factors.
What is a non-spontaneous reaction that absorbs free energy from its surroundings?
Endothermic
What is non reaction?
a non spontaneous reaction is a reaction that doesnt occur naturally and it normally tends to favor the reactants of a chemical reaction. Another thing is that it doesnt really produce free energy
What are a set of conditions would result in a reaction that is unambiguously non-spontaneous?
endothermic, increasing entropy
