Question:

What is the unit of rate of reaction?

Options:

mole L-1 s-1

mole L-2 s-1

mole L-1 s-2

mole L2 s-1

Correct Answer:

mole L-1 s-1

Explanation:

Rate of reaction is defined as the rate of change in concentration of either reactants or products in a unit interval of time.

A → B

Rate = -\(\frac{Δ[A]}{ΔT}\) =  +\(\frac{Δ[B]}{ΔT}\) 

Rate = mole L-1 s-1
