Hello everyone, I'm doing some practice problems for my final exam. I came across this question: «The Haber process is being used at a pressure of 76 000 mmHg at a temperature of 450°C. Gaseous ammonia is cooled and collected after its production, in order that its temperature does not exceed 132,35°C. What is the maximum pressure in kPa that ammonia must be in to not exceed that temperature? » So, the answer key of the previous exam I took it from says 5680 kPa. However, I find that a bit weird. It's a basic application of P1/T1=P2/T2... First of all, isn't 76 000mmHg the pressure of all the gases, including H2 and N2? Then, it is said that ammonia is collected, changing the volume of the recipient? What do you think?
