On the surface of polar stratospheric clouds, hydrolysis of chlorine nitrate gives A and B while its reaction with HCl produces B and C. A, B and C are, respectively
- \(HOCl, HNO_3, Cl_2\)
- \(Cl_2, HNO_3, HOCl\)
- \(HClO_2, HNO_2, HOCl\)
- \(HOCl, HNO_2, Cl_2O\)
The Correct Option is A
Solution and Explanation
On the surface of polar stratospheric clouds, hydrolysis of chlorine nitrate as
\(ClNO_2+H_2O⟶HOCl(A)+HNO_3(B)\)
\(ClNO_2+HCl⟶Cl_2(C)+HNO_3(B)\)
Hence \(A, B\) and \(C\) are \(HOCl, HNO_3\) and \(Cl_2\), respectively.

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
