For the reaction 2 A + 4 B → 2 C + 4 D, what is the absolute magnitude of the rate of change for [B] when [C] is increasing at 6.6 M/s?

Question

For the reaction 2 A + 4 B → 2 C + 4 D, what is the absolute magnitude of the rate of change for [B] when [C] is increasing at 6.6 M/s?

Answer 1

2A + 4B ==> 2C + 4D

The [B] decreases at twice that rate that [C] increases because it takes 4 moles of B to produce 2 moles of C.

The absolute magnitude of the rate of change for [B] = 6.6 M/s x 2 = 13.2 M/s
