It is found that a residence time of 10 minutes is required to achieve 90% conversion in a PFTR at 50C and 5 minutes at 60C. Part a What residence time (to the nearest 0.1min ) will be required to achieve 99% conversion? Part b What is the activation energy to the nearest 0.1kcal/mol ? Assume the gas constant is 2cal/molK. Part c What temperature (to the nearest 0.1C ) is required to ochieve 90% conversion with a residence time of 1 minute
