What is activation energy.

A+B rarr C, DeltaH = +60 kJ/mol E_(a_f) is 150 kJ. What is the activation energy for the backward reaction ?

A reaction is carried out at 600 K . If the same reaction is carried out in the presence of catalyst at the same rate and same frequency factor, the temperature required is 500 K . What is the activation energy of the reaction, if the catalyst lowers the activation energy barrier by 20 KJ//mol ?

The rate constant of a reaction at temperature 200 K is 10 times less than the rate constant at 400 K. What is the activation energy (E_(a)) of the reaction ? (R = gas constant)

What is the activation energy (KJ/mol) for a reaction if its rate constant doubles when the temperature is raised from 300 K to 400 K ? (R="8.314 J mol"^(-1)"K"^(-1))

What is the activation energy for the reverse of this reaction? N_(2)O_(4)(g)rarr2NO_(2)(g) Data for the given reaction is : DeltaH=+54 kJ and E_(a)=+57.2kJ :

What is the activation energy for a reaction if its rate doubles when the temperature is raised from 20^(@)C to 35^(@)C ? (R = 8.314 J "mol K"^(-))

The rate of reaction increases with increase in activation energy.

Activation energy is:

Reaction with low activation energy are ............ and the reactions with high activation energy are ...........
