Hello!
The pressure of the gas when it's temperature reaches 928 °C is 3823,36 kPa
To solve that we need to apply
Gay-Lussac's Law. It states that the pressure of a gas when the volume is left constant (like in the case of a sealed container like an aerosol can) is proportional to temperature. This is the relationship derived from this law that we use to solve this problem:
![P2= \frac{P1}{T1}*T2= \frac{103 kPa}{25}*928=3823,36 kPa](https://tex.z-dn.net/?f=P2%3D%20%5Cfrac%7BP1%7D%7BT1%7D%2AT2%3D%20%5Cfrac%7B103%20kPa%7D%7B25%7D%2A928%3D3823%2C36%20kPa)
Have a nice day!
Answer:
Step 1) hydrolysis using NaOH/H2O to form benzylalcohol
Step2) oxidation to Carboxylic acid using KMnO4 followed by decarboxylation to form benzene
3) friedel craft acylation using CH3COCl/AlCl3
Explanation:
The above 3 steps will yield acetophenone from methylbenzoate
