WebWhat will be the unit of rate constant (k)for a third order reaction? A s−1 B mol2L−2s C mol−2L2s−1 D mol−1L−2s Solution The correct option is Cmol−2L2s−1 Generalized formula for the unit of rate constant (k)for a nthorder reaction. Let , A→Products is a nthorder reaction. Rate (R)=k[A]n Units of k=Units of rateUnits of [A]n WebA rate law shows how the rate of a chemical reaction depends on reactant concentration. For a reaction such as aA → products, the rate law generally has the form rate = k[A]ⁿ, …

Order of Reaction - Definition and Explanation of …

WebUnit of k=1/time taken * concentration. Unit of k=1/t*mol L-1. Unit of k=mol -1 L t-1. General method /Alternative method to find the units of the rate constant: Let us consider any nth order reaction. n*A → B (Here A is the reactant and B is the product of the reaction) Now we can write rate=k [A]n. K=rate/ [A]n. dishanywhere.com activated

Solved QUESTION 10 Which of the following would be a - Chegg

WebMore generally speaking, the units for the rate constant for a reaction of order (m +n) ( m + n) are mol1−(m+n) L(m+n)−1 s−1. mol 1 − ( m + n) L ( m + n) − 1 s − 1. The table below summarizes the rate constant units for common reaction orders. Note that the units in the table can also be expressed in terms of molarity ( M) instead of mol/L. WebTherefore, the unit of the rate constant for the third-order reaction is. k = m o l 1-n L n-1 s-1 k = m o l 1-3 L 3-1 s-1 k = m o l-2 L 2 s-1. Suggest Corrections. 1. Similar questions. Q. The units of rate constant and rate of reaction are identical for. Q. Units of rate constant of a first order reaction is : WebSo the complete order of the reaction is the sum of x and y.
