0.8 x10^-1 mol / (L s)

Explanation:

2A + B - > 2C + D

For the reaction above, the differential rate is usually expressed as;

Rate = - (1 / 2) Δ[A] / Δt = - Δ[B] / Δt

The negative sign denotes disappearance.

Upon comparing; (1 / 2) Δ[A] / Δt = Δ[B] / Δt

If initial rate of disappearance of A is 1.6x10^-1 mol / (L s);

That means

Δ[B] / Δt = 1.6x10^-1 mol / (L s) / 2

Δ[B] / Δt = 0.8 x10^-1 mol / (L s)

The initial rate of disappearance of B = 1.6x10^-1 mol / (L s)
