A well-mixed continuous stirred tank reactor is to be used for the decomposition of an ester (E) by a first order reaction in the liquid phase. The feed rate is 0.04 m²s² and the concentration of E in the feed, CEO = 15 kmol m. Given the rate constant, kɛ = 0.02 s for the reactor conditions (25°C), and the CSTR volume is 1.8 m, what will be the concentration of ester in the stream leaving it? 2. In the above reaction, the activation energy is 50,000 J mol". What is the value of the rate constant at 50 °C? As part of a plant improvement programme, the CSTR reactor will be redesigned to operate at 50 °C using the same feed concentration, feed rate of 0.04 m's' and an outlet conversion of ester equal to 80 %. What is the required reactor volume in this case?

Transcribed Image Text:A well-mixed continuous stirred tank reactor is to be used for the
decomposition of an ester (E) by a first order reaction in the liquid phase.
The feed rate is 0.04 m²s² and the concentration of E in the feed, CEO = 15
kmol m. Given the rate constant, kɛ = 0.02 s for the reactor conditions
(25°C), and the CSTR volume is 1.8 m, what will be the concentration of
ester in the stream leaving it?
2.
In the above reaction, the activation energy is 50,000 J mol". What is the
value of the rate constant at 50 °C? As part of a plant improvement
programme, the CSTR reactor will be redesigned to operate at 50 °C using
the same feed concentration, feed rate of 0.04 m's' and an outlet
conversion of ester equal to 80 %. What is the required reactor volume in
this case?
