X2 + Y2 ---> X2Y2 rate = k[X2]A reaction and its experimentally determined rate law are represented above. A chemist proposes two different possible mechanisms for the reaction, which are given below.Mechanism 1 Mechanism 2X2 ---> 2X (slow) X2 ---> 2X (slow)X + Y2 ---> XY2 (fast) X + Y2 ---> XY + Y (fast)X + XY2 ---> X2Y2 (fast) X + XY ---> X2Y (fast)X2Y + Y ---> X2Y2 (fast)Based on the information above, which of the following is true?Both mechanism 1 and 2 are consistent with the rate law.Only mechanism 2 is consistent with the rate law.Neither mechanism 1 nor mechanism 2 is consistent with the rate law.Only mechanism 1 is consistent with the rate law.

Answer:

Answer : Both the mechanisms are consistent with the rate law

Explanation:

Both the reactions are consistent with the rate law.

This is because , the rate law tells us that , the rate is determined by the "Slowest step" in the reaction. According to the given reaction ,

In both the mechanisms ,

[tex]X_2[/tex]⇒[tex]2X[/tex] is the slowest step or RATE DETERMINING STEP .

And thus ,

The rate is proportional only to by the concentration of [tex][X_2][/tex].

Answer : Both the mechanisms are consistent with the rate law.

Both the mechanism are consisted of same slow step in the reaction. Thus, the rate law has been constituted with both mechanism. Hence, option A is correct.

The rate of reaction has been defined as the rate for formation of product and depletion of reactant. The rate of reaction has been given by the dependence of the product formation on the reactant concentration.

In a multistep mechanism reaction, the rate of reaction has been dependent on the slowest step.

Both the mechanism proposed has been consisted of the formation of X as the slowest reaction. Since slowest reaction has been the rate determining step, the rate of reaction has been dependent on the concentration of X.

Both the mechanism are consisted of same slow step in the reaction. Thus, the rate law has been constituted with both mechanism. Hence, option A is correct.
