2A B + C

Two trials of the above reaction are run. The concentration of A in the second reaction is twice that in the first. It is found that the initial rate of the reaction in the first trial is the same as that in the second trial. This indicates that the reaction is ...

zero order in [A]

first order in [A]

second order in [A]

third order in [A

Trial PNO PH2 Initial Rate 1 1 atm 1 atm 0.02 atm/s 2 2 atm 1 atm 0.16 atm/s 3 1 atm 2 atm 0.04 atm/s

Explanation / Answer

A) answer : 3

from data 1 & 2 NO pressure increases 2 times rate becomes 8 times . so with respect to NO the order is = 3

B) answer : 1

from data 1 & 3 H2 pressure increases 2 times rate becomes 2 times . so with respect to H2 the order is = 1.

C) answer : zero order in [A]

here rate = k [A]^n

if n= 0 that is zero order.

for zero order rate is independent of concentration of reactants.
