In which one of the following reactions, rate constant has the unit \(\mathrm{mol} \mathrm{L}^{-1} \mathrm{~s}^{-1}\) ?
- A Acid catalysed hydrolysis of \(\mathrm{CH}_3 \mathrm{COOCH}_3\)
- B \(\mathrm{CHCl}_3+\mathrm{Cl}_2 \longrightarrow \mathrm{CCl}_4+\mathrm{HCl}\)
- C \(2 \mathrm{NO}(g)+\mathrm{O}_2(g) \longrightarrow 2 \mathrm{NO}_2(g)\)
- D Decomposition of \(\mathrm{HI}\) on the surface of gold
Answer & Solution
Correct Answer
(D) Decomposition of \(\mathrm{HI}\) on the surface of gold
Step-by-step Solution
Detailed explanation
The given unit of the rate constant i.e.
mole \(\mathrm{L}^{-1} \mathrm{~s}^{-1}\) suggests that the reaction is of zero order.
So, among the given options, decomposition of \(\mathrm{HI}\) on the surface of gold is a zero order reaction.
mole \(\mathrm{L}^{-1} \mathrm{~s}^{-1}\) suggests that the reaction is of zero order.
So, among the given options, decomposition of \(\mathrm{HI}\) on the surface of gold is a zero order reaction.
