Effects of inerts on T and X

1. The following conversion temperature relationship is for a adiabatic reaction, A -> B, containing 50% inerts:




Sketch X vs. T for when a) the inerts are increased to 75% and b) when the inerts are decreased to 25%.

Solution


2. The following conversion temperature relationship is also for an adiabatic reaction, A -> B, containing 50% inerts:




Sketch X vs. T for when a) the inerts are increased to 75% and b) when the inerts are decreased to 25%.

Part 1

The following conversion temperature relationship is for a adiabatic reaction, A -> B, containing 50% inerts:




Sketch X vs. T for when a) the inerts are increased to 75% and b) when the inerts are decreased to 25%.

Solution




As inerts are increased, you reach the same conversion at a lower temperature.

Part 2 

The following conversion temperature relationship is also for an adiabatic reaction, A -> B, containing 50% inerts:




Sketch X vs. T for when a) the inerts are increased to 75% and b) when the inerts are decreased to 25%.

Solution

 

As you increase inerts, there is more sensible heat to supply the reaction and the temperature does not drop as much when the inerts are increased.
