Question

What is zero order reaction? Explain with suitable example.

Answer 1

Reaction in which concentration of the reactants do not change with time and the concentration rates remain constant throughout are called zero order reactions.

$A\to Product$

Example:

$H_2+C{l}_2\stackrel{hv}{\to }2HCl$

$Rate=k\left[H_2{]}^0\right[C{l}_2{]}^0$

$Rate=k$
