Nitric oxide (NO) decomposes on the surface of a heterogeneous catalyst to form N2 and O2. A plot of 1/[NO] vs. time is linear. The reaction is:

A)Third order in NO.

B)Zero order in NO.

C)The reaction order cannot be determined without more data.

D)First order in NO.

E)Second order in NO.

Homework Answers

Answer #1

answer : E) Second order in NO.

Explanation :

2 NO   --------------> N2 + O2

here the plot of 1 / [NO] vs. time is linear. so this is second order in NO.

for zero order the plot of [NO] vs. time is curved line.

for first order the plot of ln [NO] vs. time is slightly curved line.

in second order the plot of 1 / [NO] vs. time is straight line.
