According to the Gibbs free energy equation G H - T S when could a high temperature make a reaction that was nonspontaneous at low temperature spontaneous?
when h and s are both positive
What does it mean when a candle lights by its self?
It could mean that the candle wick was composed of or covered with a substance that can undergo spontaneous combustion, or that it can catch fire at room temperature by chemical reaction. There is no supernatural possibility behind a candle lighting apparently by itself.
Why the rate of reaction of lithium with water increases over time?
The temperature could increase as the reaction progressed. Higher temperatures would create a faster reaction.
What changes could you use to increase the atom economy in a reaction?
Addition of a catalyst or increasing the temperature will increase the rate of a chemical reaction.
How would you know if a reaction was endothermic or exothermic?
An endothermic reaction is one in which thermal energy, or heat, is absorbed. If heat is absorbed in the reaction process, it is endothermic. By monitoring the temperature of the reactants in a reaction, an observer could identify an endothermic reaction through observation of a decrease in the temperature.

What is a synonym for spontaneous?
For a reaction, synonyms could include automatic, reflexive, or instinctive. For a spontaneous person : impulsive, impetuous, or extemporaneous.
What determine whether a reaction took place?
Use the following equation: delta G = delta H - T*deltaS. A reaction is spontaneous if delta G is negative. A reaction will always be spontaneous (under any temperature) only if the change in enthalpy (delta H) is negative and the change in entropy (delta S) is positive. If this is not the case, the reaction will only be spontaneous (negative delta G) for a range of temperatures (or could be always non-spontaneous)
What is the French Revoultion?
A spontaneous reaction to a bankrupt, inept and unresponsive government that could not provide bread or hope.

Is water temperature could affect the reaction of table salt?
Yes.
What does it mean when are reaction is spontaneous?
The reaction happens by itself.
