Answer:
Units of k = 
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}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7BRate%7D%7B%5BX%5D%7D%3D%5Cfrac%7BM%2Fs%7D%7BM%7D%3Ds%5E%7B-1%7D)
Units of k =

Answer:
Explanation:
The metric system is a system of measurement that uses the meter, liter, and gram as base units of length (distance), capacity (volume), and weight (mass) respectively.
To measure smaller or larger quantities, we use units derived from the metric units
metric-system
The given figure shows the arrangement of the metric units, which are smaller or bigger than the base unit.
The units to the right of the base unit are smaller than the base unit. As we move to the right, each unit is 10 times smaller or one-tenth of the unit to its left. So, a ‘deci’ means one-tenth of the base unit, ‘centi’ is one-tenth of ‘deci’ or one-hundredth of the base unit and ‘milli’ is one-tenth of ‘centi’ or one-thousandth of the base unit.
The units to the left of the base unit are bigger than the base unit. As we move to the left, each unit is 10 times greater than the unit to its right. So, a ‘deca’ means ten times of the base unit, ‘hecto’ is ten times of ‘deca’ or hundred times of the base unit and ‘killo’ is ten times of ‘hecto’ or thousand times of the base unit.
