The following reaction occurs in aqueous solution: nh4 + (aq) + no2 - → n2 (g) + 2h2o (l) the data below is obtained at 25â°c. [nh4 +] (m) [no2 -] (m) initial rate (m/s) 0.0100 0.200 3.2 ã— 10-3 0.0200 0.200 6.4 ã— 10-3 the order of the reaction in nh4 + is

The order with respect to is 1.

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

k= rate constant

x = order with respect to

y = order with respect to A

n = x+y = Total order

From trial 1:    (1)

From trial 2:    (2)

Dividing 2 by 1 :

therefore x=  1

Thus order with respect to is 1.
