What are the units of k in the following rate law?. The units for k are whatever is needed so that substituting into the rate law expression affords the appropriate units for the rate. The units of k for a zero-order reaction are Ms the units of k for a first-order reaction are 1s and the units of k for a second-order reaction are 1 Ms. S-1 min-1 hr-1 etc.

Rate kx2Y 35 What are the units of k in the following rate law. Rate kXY12 Question options. Zero Order Reactions rate kA 0 Mt k k units.

If you are having trouble with Chemistry Organic Physics Calculus or Statistics we got your back. What are the units of k in the following rate law. So option D is correct.

The units for k should be mol 2 L 2 s so that the rate is in terms of molLs. General formula of unit of the different order of reactions is M 1-n s-1. Since the rate has to have a value of Ms we can compute the units of k for.

The rate of the reaction is proportional to the square of the concentration of the reactant. From the rate equation we can seethe reaction is a first order reactionas it depends on the 1 degree power of the conc. See Page 1 25.

I dont understand how to get the rate or anything. Let us help you simplify your studying. The units for k should be mol 2 L 2 s so that the rate is in terms of molLs.

K Ms-1 M-n M1-ns-1. The units for k are whatever is needed so that substituting into the rate law expression affords the appropriate units for the rate. Created by Yuki Jung.

What are the units of k in the following rate law. In this example the concentration units are mol 3 L 3. According to rate law expression the rate of reaction is depend on the concentration of X and Y.

SI unit of second order reaction M 1-2 s-1 M-1 s-1. Rate Constant k has UNITS. This problem has been solved.

X 2 Y 4 Z Rate kXY 2nd order. Rate KXY2 1M S2 1M2 S M2s M2s 1M3s. The units for the rate of a reaction are molLs.

What are the units of k in the following rate law. Rate kX Y 36 What are the units of k in the following rate law. Can some one explain this and how it works.

In the case of a zero-order reaction the rate constant k will have units of concentrationtime such as Ms. Of X So unit of k will be 1 s You can match using the rate law. Step-by-step answer 100 4 rating 0856 4 0.

Google Classroom Facebook Twitter. Ms Mmin Mhr etc. In this example the concentration units are mol 3 L 3.

Rearranging the rate equation the value of the rate constant k is given by. NO2g O3g — NO3g O2g NO2i M O3i M Initial Rate M-1s-1 010 033 142 010 066 284 025 066 710 a Rate 1360 M-25s-1 NO2 25 O3 b Rate 227 M-25s-1 NO2O3 25 c Rate 43 M-1s-1 NO2O3 d Rate 430 M-2s-1 NO2 2 O3 e Rate 130 M-2s-1 NO2O3 2 Please help if you can. This question is a common exam question and in this v.

The rate law for a zero-order reaction is rate k where k is the rate constant. Finding the rate law rate constant and the rate constant units is all explained in a few simple steps. K Rate A x B y Therefore the units of k assuming that concentration is represented in molL -1 or M and time is represented in seconds can be calculated via the following equation.

Rate k reactant y Units of rate units of rate constant units of concentration y Units of rate constant frac Units of rate Units of concentrationy frac Ms My. Show transcribed image text. Our videos will help you understand concepts solve your homework and do great on your exams.

Rate k X Y12 a Ms b M1s1 c M12s1 d M12s1 e M1s12 26. What are the units of k in the following rate law. What is the overall order of the following reaction given the rate law.

First Order Reactions rate kA Mt k M k units. Order of reaction 11 2. The units for the rate of a reaction are molLs.

Second Order Reactions rate kA 2 rate kAB Mt k M 2. Plot of Concentration Versus Time for a Zero-Order Reaction. A simplified rate law can be expressed generically in the following way.

This is the 2 nd order reaction. Rate kXY Ms k M x M Ms k M² therefore k 1Ms to make the units consistent.
