1. The problem statement, all variables and given/known data For the design of a reactor I need to calculate the pressure inside the closed reactor. Reactor volume = 75,36 ml Mixture inside the reactor = 30 ml HSO (5%) Temperature = 150 °C 3. The attempt at a solution I was thinking I will need the steam tables for water - sulfuric acid, but since it is a very diluted mixture I could just use the steam tables for water. Anyhow I hoped somebody could help me on the way of solving this problem! Many thanks in advance! Regards!
