Question
For the complex reaction A 
product
Ea1 = 180 kJ/mole Ea2 = 80 kJ/mole
Ea3 = 50 kJ/mole
Over all rate constant K is related to individual rate constant by the equation K =
Activation energy (KJ/mol) for the overall reaction is ?
productEa1 = 180 kJ/mole Ea2 = 80 kJ/mole
Ea3 = 50 kJ/mole
Over all rate constant K is related to individual rate constant by the equation K =
Activation energy (KJ/mol) for the overall reaction is ?
Options
A.150
B.140
C.100
D.None of these
Solution
Ea = 2/3 [Ea1 + Ea2 - Ea3]
Ea = 2/3 [180 + 80 - 50]
Ea = 140
Ea = 2/3 [180 + 80 - 50]
Ea = 140
