Q.
The first order gaseous decomposition of N2O4 into NO2 has a k value of 45×103s−1 at 1∘C and an energy of activation of 58kJmol−1 . At what temperature would be 1.00×104s−1 ?
According to Arrhenius equation logK1K2=2.303REa(T1T2T2−T1) log4.5×1031×104 =2.3030×8.314JK−1mol−158×1000Jmol−1×(274T2T2−274) ⇒T2=2827≈283K
