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.

The angle of the rays of the sun strike a broken bottle in a ditch at 10 00 am At 3 45 pm the surrounding dry grass catches fire Was this a spontaneous reaction?
Yes, this was a spontaneous reaction. A reaction is said to be spontaneous if it occurs without being driven by some outside force. There are two driving forces for all chemical reactions. The first is enthalpy, and the second is entropy.
When a chemical reaction has a negative delta G is the reaction exothermic or endothermic?
When a chemical reaction has a negative delta G, the reaction is exothermic because delta G is the change in energy of a system and the change in its entropy. If the effect of a reaction is to reduce G, the process will be spontaneous so delta G is negative. Hope this helps :)
What is another term for chemical change?
A chemical change is a chemical reaction.
Define chemical reaction and chemical equation?
We see the chemical reaction but we write the chemical equation.
According to the Gibbs free energy equation what is the temperature range for which the formation of liquid bromine is spontaneous?
The reaction is spontaneous below 743 K.
A chemical reaction has a positive ΔH value and a positive ΔS value Under what conditions is the reaction spontaneous?
The reaction is spontaneous only at high temperatures.
What redox conditions will produce a spontaneous reaction?
The sum of the voltages of the half-reactions is positive.
What does a positive cell voltage mean?
The reaction is spontaneous.
What can be said about a redox reaction that has a positive potential?
. The reaction will be spontaneous.
What does the term spontaneous mean in a chemical reaction?
This is a very fast reaction.
What is a chemical reaction that happens quickly?
Spontaneous combustion
What makes chemical reaction spontaneous?
Stability of the products as compare to stability of reactants.
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 happens in an endergonic reaction?
An endergonic reaction is a chemical reaction in which the standard change in free energy is positive.
Select all the conditions below that are most likely to result in a spontaneous chemical reaction or process?
-ΔH +ΔS T high -ΔH -ΔS T low
What is a chemincal reaction?
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Chemical reactions can be either spontaneous, requiring no input of energy, or non-spontaneous, typically following the input of some type of energy, such as heat, light or electricity.
