Why does a high temperature favor a nucleophilic elimination over nucleophilic substitution?
A high temperature increases the energy of the system, allowing for more kinetic energy that promotes elimination reactions over substitution reactions. In elimination reactions, the leaving group is expelled with the nucleophile attacking the electrophilic center simultaneously. In contrast, in substitution reactions, the nucleophile replaces the leaving group directly.

What is the mechanism for the reaction between bromine and cyclohexane and state the conditions favor the reaction?
The reaction between bromine and cyclohexane involves substitution of a hydrogen atom in cyclohexane with a bromine atom, forming bromocyclohexane. This reaction is a free-radical substitution reaction. Conditions favoring the reaction include the presence of light or heat to initiate the free radical formation and the use of a radical initiator such as peroxides.
How will increasing the temperature affect the equilibrium?
Increasing the temperature of a system at equilibrium will shift the equilibrium position in the endothermic direction to absorb the added heat. This change will favor the reaction that absorbs heat and produces more heat to counteract the temperature increase. Similarly, decreasing the temperature will favor the exothermic direction to produce more heat to counteract the temperature decrease.
Why iodination of alkane is irreversible?
Iodination of alkanes is typically irreversible because once the iodine atom undergoes a substitution reaction with a hydrogen in the alkane, a strong C-I bond is formed making it difficult to reverse the reaction. Additionally, the reaction conditions usually do not favor the removal of the iodine atom from the alkane.
How is temperature affect the spontaneity of a reaction with positive H and S?
An increase in temperature generally makes reactions with positive enthalpy (ΔH) and positive entropy (ΔS) values more spontaneous. This is because at higher temperatures, the increase in the TΔS term can outweigh the positive ΔH term in the Gibbs free energy equation (ΔG = ΔH - TΔS), resulting in a more negative ΔG and thus a more spontaneous reaction.
What transition metal that is liquid at room temperature and is sometimes used in outdoor security lights?
Mercury is the transition metal that is liquid at room temperature and is sometimes used in outdoor security lights due to its properties of being a good conductor of electricity and emitting light when ionized. However, due to its toxicity, mercury is being phased out in favor of more environmentally friendly alternatives.
When the Australian economy was based on import- substitution manufacturing?
protectionist policies were emphasized
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 is the correct for to do a favor or to make a favor?
do a favor -- Will you do me a favor? or ask a favor -- Can I ask you a favor?
What is an imine?
An imine is a nitrogen analogue of an aldehyde or ketone, where a nitrogen atom replaces the oxygen atom in the carbonyl group. It contains a carbon-nitrogen double bond. Imine formation occurs through a condensation reaction between a primary amine and a carbonyl compound.
When the heat shifts the direction of the reaction there has been a change in concentration and equilibrium will then be affected?
Yes, a change in temperature can shift the equilibrium of a reaction by changing the concentrations of reactants and products. The direction of the shift depends on whether the reaction is endothermic or exothermic. An increase in temperature will favor the endothermic reaction, while a decrease will favor the exothermic reaction.
The abolitionists were in favor of outlawing slavery. true?
True. Abolitionists were individuals who advocated for the complete elimination and prohibition of slavery, believing it to be a cruel and immoral practice. Their efforts played a significant role in the eventual abolition of slavery in various countries around the world.
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 is the verb for 'favor'?
The verb for 'favor' is 'to favor'.
In low temperature which factors favor a forward reaction?
In low temperatures, factors such as an exothermic reaction, a decrease in entropy, and the presence of a catalyst can favor a forward reaction. Lower temperatures decrease the kinetic energy of particles, allowing for better control over the reaction conditions towards the desired outcome.
What is the word for 'favor' in Spanish?
para favor
What are mercury thermometers used to measure?
Mercury thermometers are used to measure body temperature, room temperature, and other temperatures in a variety of settings. However, due to the toxicity of mercury, their use has decreased in favor of digital thermometers.
