Question

Which unit can be used to express the rate of a reaction? A. mL / s B. mL / g C. g / mL D. mL / mol E. s / mL

Answer 1

A. mL/s.

Step-by-step explanation:

• The rate of the reaction is the change in the concentration of the reactants (decrease) or the products (increase) with time.

Rate of the reaction = Δ[C]/Δt.

If we take the volume (mL) expressing the concentration. So, the unit of the rate of the reaction is (mL/s).
