The gas produced by treating an aqueous solution of ammonium chloride with sodium nitrite is
- \(NH_3\)
- \(N_2\)
- \(N_2O\)
- \(Cl_2\)
The Correct Option is B
Solution and Explanation
\(N_2\) gas is produced by treating an aqueous solution of ammonium chloride with sodium nitrite.
\(NH_4Cl(aq)\) + \(NaNo_2(aq)\)\(⟶\)\(N_2(g)\) \(+ 2H_2O(l)\) \(+ NaCl(aq)\)
Ammonium chloride Sodium nitrite Nitrogen gas Water Sodium chloride

Rate of a Chemical Reaction
The rate of a chemical reaction is defined as the change in concentration of any one of the reactants or products per unit time.
Consider the reaction A → B,
Rate of the reaction is given by,
Rate = −d[A]/ dt=+d[B]/ dt
Where, [A] → concentration of reactant A
[B] → concentration of product B
(-) A negative sign indicates a decrease in the concentration of A with time.
(+) A positive sign indicates an increase in the concentration of B with time.
Factors Determining the Rate of a Reaction:
There are certain factors that determine the rate of a reaction:
- Temperature
- Catalyst
- Reactant Concentration
- Chemical nature of Reactant
- Reactant Subdivision rate
