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 :

A first order reaction is found to have a rate constant, k=7.39 xx 10^(-5)s^(-1) . Find the half life of the reaction.

Consider the following reactions at 300 K. A rarr B (uncatalysed reaction) Aoverset("catalyst")rarrB (catalyst reaction) The activation energy is lowered by 8.314"KJ mol"^(-1) for the catalysed reaction. How many times the rate of this catalysed reaction greater than that of uncatalysed reaction?(Given e^(3.33)=20)

The activation energy for an uncatalysed reaction is less than that for a catalysed reaction. What do you conclude from the above statement ?

The rate of a catalysed reaction at 27^(@)C is e^(2) times the rate of uncatalysed reaction at 727^(@)C . If the catalyst decreased the activation energy by 6 Kcal/mol, the activation energy of uncatalysed reaction is (consider the same value of pre-exponential factors in both cases):

Temperature coefficient for a first order reaction is 2 .If the half life for the reaction at 25^(@)C is 10min, what would be half life of same reaction at 45^(@)C ?

Given that the normal energy of the reactant and produce are 40J and 20 J respectively and threshold energy of the uncatalysed reaction is 120 J.If the rate of uncatalysed reaction at 400 K becomes equal to the rate of catalysed reaction at 300 K, then what will be the activation energy of the catalysed forward and backward reactions respectively ?

Given : AhArrB+C, DeltaH=-"10 kcals" , the energy of activation of backward reaction is "15 kcal mol"^(-1) . If the energy of activation of forward reaction in the presence of a catalyst is "3 kcal mol"^(-1) the catalyst will increase the rate of reaction at 300 K by the number of times equal to
