Question

What are the units of k in the following rate law?Rate = k[X]s/MM/s1/s1/MsMs

Answer 1

Answer:

Units of k = $s^{-1}$

Explanation:

According to the law of mass action, the rate of a reaction is determined as the product of the active concentration of the reactant each raised to their experimentally determined coefficients which are known as order.

So, given that:-

Rate = k [X]

Rate of the reaction is also, the change in the concentration per unit time. So, the units of rate of a reaction is :- M/s

Units of [X] = M

So,

$k=\frac{Rate}{[X]}=\frac{M/s}{M}=s^{-1}$

Units of k = $s^{-1}$
