Activation Energy |Effect of catalyst #!#Ostwald Isolation Method

Rate of reaction at "400K" with " catalyst is equal to rate of reaction at "500K" without catalyst.What will be the activation energy of reaction if the catalyst lower the activation energy by "20KJ/mol

What is meant by activation energy? How is activation energy affected by i) Use of catalyst ii) rise in temperature.

Activity And Selectivity Of Catalysts

Rate of reaction in absence of catalyst at 700 K is same as in presence of catalyst at 500 K. If catalyst decreases activation energy barrier by 30 kJ/mole, determine activation energy in presence of catalyst. (Assume 'A' factor to be same in both cases)

What is the effect of catalyst on activation energy ?

A catalyst decreases activation energy by 15 Kcal and it is observed that rate of reaction in absence of catalyst at 400K is same as rate of reaction in presence of catalyst at 300 K. The activation energy in absence of catalyst will be :
