Report problem The rate law for the reaction NH4+(aq) + NO2-(aq) N2(g) + 2H20() is given by rate k| NH' || N°2-1. At a certain temperature, the rate constant is 2.50 x 10-4 Ars. Calculate the rate of the reaction at that temperature if LNH4j = 0.301 M and NO2- 0.200 M. x 10 Mis Enter your answer in scientific notation.

Explanation / Answer

The reaction is NH4+ + NO2- --------> N2 + 2 H2O

The rate of reaction is given by

rate = k [NH4+] [NO2-]

Given k = 2.5x10-4 /Ms

[NH4+] = 0.301 M

[NO2-] = 0.201 M

Thus rate of the reaction under given condistions

rate =  2.5x10-4 /Ms x 0.301 M x 0.200M

= 1.5x10-5M/s
