Rate \(=\mathrm{k}\left[\mathrm{PH}_{3}\right]\)
It is dependent on surface coverage because at low pressure, surface area covered is proportional to partial pressure
of \(\mathrm{PH}_{3}\) and it is first order w.t.t. \(\mathrm{PH}_{3}\)
\(\theta=\frac{k P}{1+k P}\)
\(\theta=\) fraction of surface area covered at low pressure \(\theta=\mathrm{k} \mathrm{P}\)
$A_2 $ $\rightleftharpoons$ $ A + A$ ....... (ઝડપી) ;
$A + B_2\rightarrow AB + B$ ..... (ધીમી) ;
$ A + B \rightarrow AB$ ...... (ઝડપી)
(નજીકના પૂર્ણાંકમાં રાઉન્ડ ઑફ) (ધારી લો : $\ln 10=2.303, \ln 2=0.693$)
$2X \rightleftharpoons {X_2}$
${X_2} + Y \to {X_2}Y\,\left( {slow} \right)$
