JEE Mains · Chemistry · STD 12 - 3. Chemical kinetics
For the adsorption of hydrogen on platinum,the activation energy is \(30\,kJ\,mol ^{-1}\) and for the adsorption of hydrogen on nickel,the activation energy is \(41.4\,kJ\,mol ^{-1}\). The logarithm of the ratio of the rates of chemisorption on equal areas of the metals at \(300\,K\) is \(........\)(Nearest integer)Given: \(\ln 10=2.3 \quad R=8.3\,JK ^{-1}\,mol ^{-1}\)
- A \(4\)
- B \(6\)
- C \(8\)
- D \(2\)
Answer & Solution
Correct Answer
(D) \(2\)
Step-by-step Solution
Detailed explanation
\(K = Ae ^{-\frac{ E _{ a }}{ RT }}\) \(K _1= Ae ^{-\frac{\left( E _{ a }\right)_1}{ RT }}\) \(K _2= Ae ^{-\frac{\left( E _{ a }\right)_2}{ RT }}\) \(\frac{ K _2}{ K _1}= e ^{\frac{\left( E _{ a }\right)_1-\left( E _{ a }\right)_2}{ RT }}\)…
