Consider the following reactionsI. N2O5----->2NO2 + 1/2 O2II. SO2CI2 →SO2 + Cl2III. H2 + 12 →2HIThe correct statement about these reactions is
Correct answer: D. I and II are first order reactions
- A. I is a second order reactioN
- B. II and III are first order reactions
- C. III is a first order reaction.
- D. I and II are first order reactions
Explanation
Let's analyze each reaction:LN₂O₃→ 2NO2 + 0.502This reaction involves the decomposition of dinitrogen pentoxide (N₂O₃) into nitrogen dioxide ( NO₂) and oxygen (O2). The reaction rate depends on the concentration of N2O5, so it is a first order reaction.II. SO₂CI2 SO2 + Cl2This reaction involves the decomposition of sulfur dioxide dichloride (SO₂Cl₂) into sulfur dioxide (SO₂) and chlorine (Cl₂). The rate of this reaction also depends on the concentration of SO₂Cl2, making it a first order reaction.III. H2+I22HIThis reaction involves the combination of hydrogen gas (H₂) and iodine gas (12) to form hydrogen iodide (HI). The rate of this reaction depends on the concentrations of both H₂ and I2, making it a second order reaction.Correct (I and II are both first order reactions).Therefore, the correct statement is:d. I and II are first order reactions

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
