Aug 15, 2020 · The units for the rate of a reaction are mol/L/s. The units for k are whatever is needed so that substituting into the rate law expression affords the appropriate units for the rate. In this example, the concentration units are mol 3 /L 3 .

In chemical kinetics, a reaction rate constant or reaction rate coefficient (⁠ ⁠) is a proportionality constant which quantifies the rate and direction of a chemical reaction by relating it with the concentration of reactants. [1] For a reaction between reactants A and B to form a product C, where. the reaction rate is often found to have the form:

Oct 27, 2022 · The units for the rate of a reaction are mol/L/s. The units for k are whatever is needed so that substituting into the rate law expression affords the appropriate units for the rate. In this example, the concentration units are mol 3 /L 3 .

Molar concentration (also called molarity, amount concentration or substance concentration) is a measure of the concentration of a chemical species, in particular, of a solute in a solution, in terms of amount of substance per unit volume of solution.

The units for the rate of a reaction are mol/L/s. The units for k are whatever is needed so that substituting into the rate law expression affords the appropriate units for the rate. In this example, the concentration units are mol 3 /L 3 .

k = mol/L s or M/s or M x s-1. Let’s assume it is a first-order reaction in molecule A: rate = k [A] The units for the rate are mol/L. The rate constant is equal to: \ [k\; = \;\frac { { {\rm {rate}}}} { {\left [ {\rm {A}} \right]}}\] And now, add the units for the rate and concentration:

Express the reaction rate as moles per liter per second [mol/(L·s), or M/s]. Then determine the units of each chemical species in the rate law. Divide the units for the reaction rate by the units for all species in the rate law to obtain the units for the rate constant.

Oct 22, 2014 · So your first example mol/L -1 /s -1 is not correct - it would actually be written as mol L -1 s -1, OR mol/ (L s). It is also sometimes written as mol/L/s, but the double division is ambiguous and should be avoided unless parentheses are used. If it were mol L -1 s -2, this would mean moles per litre per second per second.

Rate laws or rate equations are mathematical expressions that describe the relationship between the rate of a chemical reaction and the concentration of its reactants. In general, a rate law (or differential rate law, as it is sometimes called) takes this form: rate=k [A]m[B]n[C]p….
