Example 14.1
Write the rate expressions for the following reactions in terms of the disappearance of the reactants and the appearance of the
products:
(a) I¯ (aq) + OCI" (aq) → Cl¯ (aq) + OI (aq)
(b) 302 (g) → 203 (g)
(c) 4NH3 (g) + 502 (g) → 4NO (g) + 6H2O (g)
Solution
(a) Because each of the stoichiometric coefficients equals 1,
[_I] V
At
A [OCI¯]
rate =

[_I0] V
(b) Here the coefficients are 3 and 2, so
