Define activation energy of a reaction.

Higher the activation energy of a reaction slower is the rate of the reaction Explain.

The activation energy of a reaction 2H I_(g) rarrH_2 + I_(2(g)) is 209.5 kJ mol^-1 at 581K. Calculate the fraction of molecules of reactants having energy equal to or greater than activation energy?

The activation energy of a reaction is 75.2 KJ mol^-1 in the absence of a catalyst and 50.14 Kjmol^-1 with a catalyst. How many times will the rate of reaction grow in the presence of the catalyst if the reaction proceeds at 25^@C ? (R = 8.314 JK^-1mol^-1)

In Arrhenius equation Can activation energy E for a reaction be zero?

The rate constants of a reaction at 500K and 700K are 0.02s^-1 and 0.07s^-1 respectively. Calculate value of activation energy for the reaction. (Given R = 8.314 JK^-1 mol^-1)

A certain reaction is 50% complete in 20 minutes at 300K and the same reaction is again 50% complete in 5 minutes at 350K. Calculate the activation energy if the reaction is of first order.

A certain reaction is 50% complete in 20 minutes at 300K and the same reaction is again 50% complete in 5 mins at 350K. Calculate the activation energy if the reaction is of first order.

In general it is observed that the rate of a chemical reaction doubles with every 10^@ rise in temperature. If the generalisation holds for a reaction in the temperature range 295K to 305K, what would be the value of activation energy for the reaction?

The rate constant of a reaction at 500K and 700K are 0.01s^-1 and 0.07s^-1 respectively. Calculate the value of activation energy for the reaction (R = 8.314 JK^-1mol^-1).

For a decomposition reaction, the values of rate constants at two different temperatures are given below: K_1 = 2.15xx10^-8 Lmol^-1s^-1 at 650k K_2 = 2.39xx10^-7 Lmol^-1s^-1 at 700k Calculate the value of activation energy for the reaction (R = 8.314 JK^-1 mol^-1 )
