Second order reaction
Second order reaction:
In this reaction, the rate of the reaction depends upon the concentration of two reacting species.
Example:
(1) Decomposition of nitrogen peroxide
2NO² --> 2NO + O², rate = K [NO²]²
(2) Reaction between H²(g) and I²(g) to from HI(g) H²(g) + I²(g) 2HI(g), rate = k[H²] [I²]
(3) Alkali hydrolysis of ester
CH³COOC²H⁵ + NaOH--> CH³COONa + C²H⁵OH, rate = k[CH³COOC²H⁵] [NaOH].
