What are differences between rapid and spontaneous combustion?
The spontaneous combustion flows very slowly and occur by self heating.
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
Why do many spontaneous reactions occur very slowly and theu don't occur instantly?
a. all reactions are endergonicb. many reactions require large inputs of activation energyc. no catalysts are present in body cellsd. there is not enough ATP in body cells
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 criteria for a spontaneous process to be called so?
the reaction must occur without energy. I.e. the rolling of a ball down a hill
What does a positive cell voltage mean?
The reaction is spontaneous.

What makes chemical reaction spontaneous?
Stability of the products as compare to stability of reactants.
What is the difference between a reaction that happens spontaneously and a reaction that doesn't?
The difference can be clarified by entropy (the second rule of thermodynamics).The reaction is more spontaneous with higher entropy, for the reactions that occur spontaneously the entropy is higher than for the ones that do not.

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.
What does it mean when are reaction is spontaneous?
The reaction happens by itself.
