The first order series reaction as shown in the bellow figure is conducted in a batch reactor. The initial concentrations of A, B and C (CA0, CB0, CC0 respectively) are all non-zero. The variation of CB with reaction time will not show a maximum, if___________________?
Correct answer: A. k2 CB0 > k1 CA0
- A. k2 CB0 > k1 CA0
- B. k CA0 > k2.CB0
- C. CB0 > CA0
- D. CA0 > CB0
Explanation
For A → B → C, B initially rises only when its formation rate, k₁C_A0, exceeds its consumption rate, k₂C_B0. If k₂C_B0 is greater, B decreases from the start and therefore has no maximum.
