1) Assertion-Reason
I- Decomposition of NH3 on Pt surface is a zero order reaction at lower concentration of NH3, but at higher concentration, the order becomes a first order reaction.

II- Rate =

a)Both correct;II explains I
b)Both correct;II dosen't explain I
c)I-True; II-False
d)I-False; II-True

2)For a given reaction, A--->P, Rate= 1x10-4 M/s when [A]=.01M & 1.41x 10-4 M/s when [A]=.02M.
Deduce the expression fr Rate Law.

3)The given reaction is-
xA-----> yB

&

(-ve sign indicates rate of dissapearance of the reactant).
Find the value of-

Hello,
I am totally confused.......
