Answer:

Humidity is the amount of moisture (water vapor) in the air. It can be expressed as absolute humidity or relative humidity. Absolute humidity is the mass of water vapor divided by a unit volume of air (grams of water/cm3 of air).

The following reaction occurs in aqueous solution: NH4 + (aq) + NO2 - â†’ N2 (g) + 2H2O (l) The data below is obtained at 25Â°C.

Answer: The order with respect to $NH_4^+$ 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.

$NH_4^++NO_2^-\rightarrow N_2+2H_2O$

$Rate=k[NH_4^+]^x[NO_2^-]^y$

k= rate constant

x = order with respect to $NH_4^+$

y = order with respect to A $NO_2^-$

n = x+y = Total order

From trial 1: $3.2\times 10^{-3}=k[0.0100]^x[0.200]^y$ (1)

From trial 2: $6.4\times 10^{-3}=k[0.0200]^x[0.200]^y$ (2)

Dividing 2 by 1 : $\frac{6.4\times 10^{-3}}{3.2\times 10^{-3}}=\frac{k[0.0100]^x[0.2000]^y}{k[0.0200]^x[0.200]^y}$

$2=2^x,2^1=2^x$ therefore x= 1

Thus order with respect to $NH_4^+$ is 1.
