For each of the following reactions, express the given rate of change of concentration of the reactants or Products in that reaction:
a.`H_(2)O_(2) + 2H^(o+) + 3l^(ɵ) rarr I_(3)^(ɵ) + 2H_(2)O`, `(-d[I^(ɵ)])/(d t) = ?`, `(-d[H^(o+)])/(d t) ? `
(b) `16H^(o+) + 2Mn_(4)^(ɵ) + 101^(ɵ) rarr 2Mn^(2+) + 8H_(2)O + 5I_(2)`, `(-d[MNO_(4)^(ɵ)])/(d t) = ?`
( c) `4NH_(3) + 5O_(2) rarr 4NO_(2) + 6H_(2)O` , `(-d[NH_(3)])/(d t) = ?`

Explanation

To solve the given question, we need to express the rate of change of concentration of reactants and products for each reaction. Let's break it down step by step.

### Part (a)

**Reaction:**
\[ H_2O_2 + 2H^+ + 3I^- \rightarrow I_3^- + 2H_2O \]

**Given:**
