Define activation energy of a reaction.

The activation energy of reaction is equal to

At 27^@C in the presence of a catalyst, the activation energy of a reaction is lowered by 10 kJ mol^-1 . The ratio of log k (catalyst)/k (uncatalysed) is

True or False : Higher the activation energy of a reaction, faster is the reaction.

Arrhenius studies the effect of temperature on the rate of a reaction and postulted that rate constant varies with temperature exponentially as k=Ae^(E_(a)//RT) . Thuis method is generally used for finding the activation energy of a reaction. Keeping temperature constant, the effect of catalyst on the activation energy has also been studied. If the rate of reaction doubles for 10^(@)C rise of temperature form 290K to 300K, the activation energy of the reaction will be approximately: a) 40 Kcal mol^(-1) b) 12 Kcal mol^(-1) c) 60 Kcal mol^(-1) d) 70 Kcal mol^(-1)

Arrhenius studies the effect of temperature on the rate of a reaction and postulated that rate constant varies with temperature exponentially as k=Ae^(-E_(a)//RT) . This method is generally used for finding the activation energy of a reaction. Keeping temperature constant, the effect of catalyst on the activation energy has also been studied. If x is the fraction of molecules having energy greater than E_(a) it will be given by : a) x=-(E_(a))/(RT) b) In x=-(E_(a))/(RT) c) x=e^(E_(a)//RT) d) Any of these

Arrhenius studies the effect of temperature on the rate of a reaction and postulted that rate constant varies with temperature exponentially as k=Ae^(E_(a)//RT) . Thuis method is generally used for finding the activation energy of a reaction. Keeping temperature constant, the effect of catalyst on the activation energy has also been studied. The pre-exponetial factor in the Arrhenius equation of a first order reaction has the unit : a) mol L^(-1)s^(-1) b) L mol^(1)s^(-1) c) s^(-1) d) dimensionless
