Decomposition of A to give B follows a two step mechansim as shown. From the mechanism identify the option which is incorrect.
`A rarr 1.5 B" "`(overall reaction)
Steps-1: `A underset(k_(2))overset(k_(1))hArr B+C" "` (fast)
Step-2: `A+C overset(k_(3))rarr 2B" "`(slow)

A

Overall rate constant of the reaction will be `k_(3)` .

B

Rate of reaction will be dependent on concentration of B.

C

Rate of reaction will be dependent on concentration of A.

D

Overall activation energy will involve activation energy of forward ad backward reaction of first and that of second step.

A consecutive reaction, A overset(K_(1))(rarr)B overset(K_(2))(rarr)C is characterised by:

The rate law expresison is given for a typical reaction, n_(1)A + n_(2) B rarrP as r = k[A]^(n)[B]^(n2) . The reaction completes only in one step and A and B are present in the solution. If the reaction occurs in more than one step, then the rate law is expressed by consdering the slowest step, i.e., for S_(N)l reaction r = k[RX] . If the eraction occurs in more than one step and the rates of the steps involved are comparable, then steady state approximation is conisdered, i.e., the rate of formation of intermediate is always equal to the rate of decompoistion of the intermediate. Conisder the reaction: [[I_(2) underset(k_(1))overset(k_(2))hArr2I("rapid equilibrium")],[H_(2)+2I overset(k_(3))rarr 2HI("slow")]] Which of the following expresison is correct?
