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.

� Gibbs Free Energy: Equilibrium Constant Nitric oxide, NO, also known as nitrogen monoxide, is one of the primary contributors to air pollution, acid rain, and the depletion of the ozone layer. The reaction of oxygen and nitrogen to form nitric oxide in an automobile engine is N2(g)+O2(g)?2NO(g) The spontaneity of a reaction can be determined from the free energy change for the reaction, ?G?. A reaction is spontaneous when the free energy change is less than zero. A reaction...
