T2=527oC⇒800k;k1=2.5×10−4
T1=327oC⇒600k;k2=1
According to Arrhenius Equation;
lnk1k2=−REa(T21−T11)
ln(2.5104)=REa(6001−8001)
ln(4000)=8.314Ea(24001)
Ea=165.431kJ,Ea≈166kJ/mol
For the reaction of H2 with I2, the rate constant is 2.5×10−4dm3mol−1s−1 at 327oC and 1.0dm3mol−1s−1 at 527∘C . The activation energy for the reaction, in kJmol−1 is:
(R=8.314JK−1mol−1)
