Question

Different order and rate?

Answer 1

Order
1. It is an experimental quantity
2. It is the sum of the powers to which the concentration terms are raised in the rate law equation
3. It may have fractional values
4. It can be Zero

(I only know differences about order and molecularity but not much about rate)
Molecularity
1. It is a theoretical concept
2. It is the number of species undergoing simultaneous collision in the reaction
3. It has only whole number values
4. It cannot be zero

Answer 2

Answer:

The Order of Reaction refers to the power dependence of the rate on the concentration of each reactant. Thus, for a first-order reaction, the rate is dependent on the concentration of a single species. ... The order of reaction is an experimentally determined parameter and can take on a fractional value.
