Question

If for the parallel reactions A→B and A→C, if the final concentration of B is 26 mol/ L and A converted is 36 mol/L, then the final concentration of C is ____

(a) 15

(b) 5

(c) 6

(d) 10

This question was addressed to me in class test.

This key question is from Parallel Reactions Design in portion Potpourri of Multiple Reactions, Design for Single & Parallel Reactions of Chemical Reaction Engineering

Answer 1

Right option is (d) 10

Easiest explanation: CA0 – CA = 36

CB = 26

CC = A converted – B formed

CC = 10 mol/L.
