To prevent di-nitration of the methy benzoate because COOMe group attached to the aromatic ring is deacitvating, hence, plus the deactivating NO2 group, a higher temperature and more acidic condition would be required to add another NO2 to the 5th carbon of the aromatic ring of the methyl 3-nitrobenzoate

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.
Why is a low temperature not used in the haber process?
A low temperature is not used in the Haber process because the reaction between nitrogen and hydrogen to form ammonia is an exothermic reaction, meaning it releases heat. Using a higher temperature allows for a higher reaction rate, but temperatures that are too high can lead to decreased ammonia yield due to the reverse reaction occurring.
Why can a catalyst speed up a reaction even at low temperature?
Because catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction increases.
What conditions will a low temperature make a reaction spontaneous?
if H and S are both negative
What are things that decrease a reaction rate?
Some factors are: low temperature, low pressure, low concentration of reactants, no stirring, coarse particles, etc.
Why is synthesis of p-nitro acetanilide carried out at low temperature?
Synthesis of p-nitro acetanilide is carried out at low temperature to minimize side reactions and to control the rate of the nitration reaction. Low temperature helps to improve the selectivity of the reaction, favoring the desired product formation over potential byproducts.
Explain why nitration are usually carried out at comparatively low temperatures?
In most of the nitration processes heat is require but relatively (as compare to sulphonation) low temperature is due to volatile nature of nitrating agent which is usually nitric acid, at higher temperature nitric acid may decompose or may escape from the reaction vessel.
What is the introduction to the preparation of m-dinitrobenzene nitration of nitrobenzene?
The preparation of m-dinitrobenzene by nitration of nitrobenzene involves reacting nitrobenzene with a nitrating agent, such as a mixture of nitric acid and sulfuric acid. The reaction is typically carried out under controlled conditions, such as low temperature and in small portions, to ensure the production of the desired m-dinitrobenzene isomer. Proper safety measures, including the use of appropriate protective equipment and a fume hood, are essential due to the hazardous nature of nitration reactions.
What is the function of the temperature?
in the sence of chemistry many reaction occured at the low temperature....dis is main advantage of low temprature

When Could A High Temperature Make A Reaction That Was Nonspontaneous At Low Temperature Spontaneous?
A high temperature can make a nonspontaneous reaction spontaneous by providing enough energy to overcome the activation energy barrier, allowing the reaction to proceed. At low temperatures, the kinetic energy of the molecules may not be sufficient for them to react, but increasing the temperature can provide the necessary energy for the reaction to occur spontaneously.
When magesium ribbon react with dilute hydrochloric acid what will be the room temperature?
This reaction is possible also at low temperature.

Under what conditions will a low temperature make a reaction spontaneous?
if H and S are both negative
why are many industrial reaction carried out at high tempratureexplain the reason by having given illustrated example?
Because if the temperature is increased, the equilibrium position moves in the direction of the endothermic reaction. and if the temperature is low the reaction would be slow.
