Answer to Question #325497 in General Chemistry for Ubajsiz

Question

Reaction Mechanism Problem:

The following pair of elementary reactions occur when atomic chlorine in the environment reacts with ozone: (12 points)

Cl+O_(3(g))→〖ClO〗_((g))+O_(2(g)) fast

〖ClO〗_((g) )+O→〖Cl〗_((g))+O_(2(g)) slow

Determine the overall reaction.

Write the rate law expression for each elementary reaction.

Identify any intermediates.

Determine the overall rate law expression.

The following equation describes how nitrogen(II) oxide, NO, reacts with hydrogen, H2: (12 points)

2NO+H_2→N_2+H_2 O_2 slow

H_2 O_2+H_2→2H_2 O fast

Determine the overall reation.

Write the rate law expression for each elementary reaction.

Identify any intermediates.

Determine the overall rate law expression.

Answer 1

Cl + O₃ = ClO^- + O₂;

ClO^- + O = Cl + O₂;

v = k * [Cl] * [O₃]

v = k * [ClO^-] * [O]
