Question

For the reaction A+2B→C under a given set of conditions, the initial rate is 0.100 M/s.


What is Δ[B]/Δt under the same conditions?

Answer 1

The rate of consumption of B will be twice that of the rate of production of C, because that is how their mole ratios are related. Thus,
Δ[B] / Δt = -0.2 M/s (negative because consumption)
