So that only one NO2+ is substituted for the hydrogen on one of the carbons in benzene , if it was above 50 degree Celsius then more than one hydrogen would be substituted and mono nitration is only one substitution of hydrogen for NO2+
Sulfuric acid acts as a catalyst in the nitration of benzene by protonating the nitric acid, which generates a more reactive electrophile (NO2+). This electrophile then attacks the benzene ring to introduce the nitro group during the nitration process.
Nitration of nitrobenzene is more difficult because the nitro group is an electron-withdrawing group, making the nitrobenzene less reactive towards electrophilic aromatic substitution reactions. In contrast, benzene is more reactive because it does not have any electron-withdrawing groups attached to it.
The evaporation temperature of benzene is around 80 degrees Celsius.
The triple point for benzene is the temperature and pressure at which benzene can exist simultaneously as a solid, liquid, and gas. For benzene, the triple point occurs at a temperature of 5.5 degrees Celsius and a pressure of 48.6 kilopascals.
Nitrobenzene is typically synthesized by nitration of benzene using a mixture of concentrated nitric acid and sulfuric acid as the nitrating agents. The reaction involves the substitution of a hydrogen atom on the benzene ring with a nitro group, resulting in the formation of nitrobenzene.
For example nitrobenzene is obtained by nitration of benzene.

Hi ,As you know from the structures of both the compounds that toluene has a methyl group on the benzene ring which is electron releasing group and hence activate the benzene ring by pushing the elctrons on the benzene ring. On the other hand nitro group on the benzene ring is electron withdrawing group which deactivates the benzene ring by withdrawing the electrons from the benzene ring . Now in the nitration attack of the nucleophile ( NO2 +) takes place. Hence reaction will takes place on that benzene faster which have more electron density on its ring which is the case of toluene.
An example of a nitration reaction is the nitration of benzene to form nitrobenzene. In this reaction, benzene reacts with a mixture of concentrated nitric acid and sulfuric acid, where the sulfuric acid acts as a catalyst. The electrophilic aromatic substitution occurs, resulting in the introduction of a nitro group (–NO₂) onto the benzene ring. This reaction is significant in organic chemistry for synthesizing various nitro compounds.

nitration of the benzene ring and gives positive
Benzene is a liquid at room temperature. The boiling point of benzene is 80.1 degrees Celsius, which means it is typically found in a liquid state at temperatures below that.
Sulfuric acid acts as a catalyst in the synthesis of nitrobenzene by nitrating benzene. It facilitates the nitration reaction by protonating the nitric acid, making it a better electrophile for attacking the benzene ring. Sulfuric acid also helps in generating the nitronium ion, which is the active species involved in the nitration process.
The specific heat of benzene is 1.75 J/g°C. You can use the formula q = mcΔT, where q is the heat added, m is the mass of benzene, c is the specific heat, and ΔT is the change in temperature. Plug in the values and solve for c.
