Question

Which of the following correctly relates conversion to the heat of adiabatic reaction?

(a) Cp ∆T(-∆HR) = XA

(b) (frac{C_p}{-H_R}) = XA

(c) (frac{C_p ∆T}{-H_R}) = XA

(d) (frac{-H_R C_p}{∆T}) = XA

Answer 1

Right option is (c) (frac{C_p ∆T}{-H_R}) = XA

For explanation: Conversion is obtained by the ratio of heat needed to raise the feed stream to the final temperature, T2 to the heat released by the reaction at T2.

 XA = (frac{C_p (T_2- T_1)}{-H_R}. )
