Chemical Engineering - Chemical Reaction Engineering - Discussion

As the reaction time increases consumption of A to produce B increase and consumption of B to produce C also increase until minimum consumption of B remain. Since the reaction is consecutive their concentration also increases from A to C. This is true if C1 and C2 are the same catalytic effect on the reaction. The Answer is C. Answer B is false in my opinion.

The reaction is characterised by maxima in the concentration of B. The maxima can occur for intermediate.
In the reaction,
A) decreases in a single-exponential phase,
B) increases exponentially, reaches some maximum value and then decays back to zero, and
C) increases exponentially.

Answer B is correct as concentration of C produced cannot be more than concentration of B produced.
