Question

In a 1st order reaction the fraction of molecules at ${450}^{o}C$ having sufficient energy (or fraction of effective collisions) is $1.92\times {10}^{-16}$.What is activation energy value of this reaction?

• A. $27.757\times {10}^{2}Jmol{e}^{-1}$
• B. $21.757\times {10}^{3}Jmol{e}^{-1}$
• C. $21.75\times {10}^{4}Jmol{e}^{-1}$
• D. None

Answer 1

The correct option is C $21.75\times {10}^{4}Jmol{e}^{-1}$
