Why does a high temperature favor a nucleophilic elimination over nucleophilic substitution?

My guess would be that Elimination reactions are much higher energy, as it breaks bonds. Higher temperature = higher energy.

What is the mechanism for the reaction between bromine and cyclohexane and state the conditions favor the reaction?
electrophilic substitution. and UV light or heat is required to all the reaction to proceed
How is temperature affect the spontaneity of a reaction with positive H and S?
∆G = ∆H - T∆S and ∆G has to be negative for the reaction to be spontaneous. So, ultimately the effect of temperature will depend on the value of ∆H. If ∆H is negative, and ∆S is positive, then temperature won't matter, and reaction will be spontaneous. If ∆H is positive, and ∆S is positive, then a high temperature will favor spontaneity. If ∆H is negative and ∆S is negative, then a low temperature will favor spontaneity. So, the answer to your question is the higher the temperature the more likely the reaction will occur spontaneously.
How does temperature affect the formation of anthocyanin?
Temperature, light, and water supply have an influence on the degree and the duration of fall color. Low temperatures above freezing will favor anthocyanin formation producing bright reds in maples. However, early frost will weaken the brilliant red color. Rainy and/or overcast days tend to increase the intensity of fall colors
Which direction of the reaction equilibrium is favored at 298 K room temperature use the reaction I2 solid to I2 gas when H 62.4 kJmol and S 0.145 kJmolK?
I2(s) --> I2(g); dH=62.4kJ/mol; dS=0.145kJ/mol. The reaction will favor the product at this temperature. Your entropy is positive and your enthalpy is also positive, so this reaction will not be spontaneous at all temperatures. But at room temperature, which is 298K, it will be spontaneous and proceed left to right. (this is the sublimation of iodine)
People favor their in-groups and when they treat other groups unfairly it is called?

What is an imine?
An imine is a functional group or chemical compound containing a carbon-nitrogen double bond. An imine can be synthesised by the nucleophilic addition of an amine to a ketone or aldehyde giving a hemiaminal -C(OH)(NHR)- followed by an elimination of water to yield the imine. However, the equilibrium in this reaction usually lies in favor of the free carbonyl compound and amine, so that azeotrope distillation or use of a dehydrating agent such as molecular sieves is required to push the reaction in favor of imine formation. For more details, see the links on the left side of this column.
When the Australian economy was based on import- substitution manufacturing?

Define quit pro quo?
Quid pro quo (From the Latin meaning "something for something")[1] indicates a more-or-less equal exchange or substitution of goods or services. English speakers often use the term to mean "a favor for a favor"
What are the factors that favor the formation of barium sulphate crystals?
temperature of heating and time for cooling of the crystals
What is the correct for to do a favor or to make a favor?

What is the word favor mean in spanish?
Favor in Spanish means the same as in English. To say "por favor" (for favor) means please. "A favor de" means in favor of. "Da me un favor" is do me a favor.
What type of weathering process causes underground erosion?
Climate can affect weathering and erosion. The 2 factors include temperature and moisture. Warm climates favor chemical weathering while cold climates favor physical weathering. Dissolving Rock.
What is the word for 'favor' in Spanish?
