How is the reaction rate influenced by energy of activation ?

Basal Metabolic Rate is influenced by

What are threshold energy and energy of activation ?

A certain endothermic reaction: Ato Product, DeltaH=+ve proceeds ina sequence of three elementary steps with the rate constant K_(1),K_(2) and K_(3) and each one having energy of activation E_(1),E_(2) and E_(3) respectively at 25^(@)C . The observed rate constannt for the reaction is equal to K_(3)sqrt((K_(1))/(K_(2))) . A_(1),A_(2) and A_(3) are Arrhenius parameters respectively. Presence of a catalyst decreasesthe energy of activation of each path by half the value of E_(1) . Assuming the other factors same, the observed energy of activation would be

With 100 kJ mol- activation energy for an uncatalysed reaction at 20°C, the catalyst lowers the energy of activation by 75%. What will be the effective rate if other conditions are same?

A: Lesser the activation energy, greater is the rate of reaction R: Activation energy of a reaction is independent of temperature

Explain the factors influencing rate of reaction.

(A)Catalyst increases the rate of reaction. (R ) Catalyst functions by lowering the energy of activation.
